1.2 IntroductionINTRODUCTION: HOW TO USE THIS MANUAL

This is a reference manual on the design, detailing, and drawing of eave extensions, canopy, and facia. Eave extensions and canopy have been operational in MBS for some time. The complete processingof facia is a new feature in the MBS software. The manual contains the earlier reference drawings oneave extensions and canopy in addition to the new reference drawings on facia.

A. HOW TO USE THIS MANUAL TO SETUP YOUR DESIRED FACIAThis process consists of deciding on the facia styles that you want to offer, filling out the DS_FACIAfile, setting the detailing methods and parameters, and running test cases to see that the desired facia isproduced by the program. The following sections describe each of these steps.

B. SELECTING YOUR DESIRED FACIA STYLESAs a software user, you may have one or many styles that you plan to use. Examples of availablefacia style are shown on the drawings listed below.

DRAWING FEATURES OF FACIAFACIA 1 With GutterFACIA 2 Vertical: Facia Panel, Arm, Back PanelFACIA 3 Sloped Facia Panel, Vertical Back PanelFACIA 4 Sloped Facia Panel, Sloped Back Panel

C. ENTERING DATA IN THE DS_FACIA FILEThe purpose in this file is to expedite the data entry for facia. When a certian facia style is selectedduring building entry, the default data on that facia style will come from the DS_FACIA file. Onselecting the facia style, many of the facia features will come into the building data file, and can beedited during building entry. Users may select one or many facia styles to have as their availablefacia.

A sample DS_FACIA file is in the last section of this manual. The following help file provides a guideon how to fill out the file. This file indicates the composition of the facia. In filling out the file you willneed to select the types of connections for the attachment beam and facia arm. The options forconnection design are shown in the section labeled "Design Drawings".

D. SELECTING THE DETAILING METHODS AND DETAILING PARAMETERSStart with detailing method drawing EX10. It lists the detailing methods that apply to the different partsof the facia. The detailing method drawings (Exi) that illustrate the detailing method are also listed.For example, suppose you plan to use bypass girts at the top of interior facia arms. Note the referenceto DM 277 on drawing EX10. This references drawing EX11 where you can select the option for thatconnection. Set the selected detailing method in the DT_METHD file. Also note the reference toparameter drawing PX24. View that drawing, select values for the detailing parameters, and set theparameters in the DT_BUILD file.

E. USING THE FACIA CONNECTION HELP FILE TO SET UP THE FACIAOne of the icons on the desk top is references MBS CONNECTIONS. Click on that icon and therewill be a number of options for connection information. Four of those options are related to facia.Suppose you are interested in connections to facia arms. Click on that option. Now you have a tablelisting the options for connections to facia arms. The column on the left lists items that can be attached

PE: Design 9


to the facia arm. Move to the heading "Girt, Top and Bottom". Move to the right on that line and youwill see the detailing method drawing as well as the parameter drawing that controls that connection.View the drawing and set the selected values in the data file. For ease of reference, a paper copy ofthe facia connection help tables are in the last section of this manual.

F. TESTING THE FACIAHaving completed the setup, select a building on which you wish to place a facia and start by enteringthe building data, including the facia data. If there is a concern for the meaning of any of the inputdata, press F1 to receive a text help file. Then, run the building as you would any other building. Manyof the programs will be processing the facia. You can learn more about each of the steps by readingthe program enhancements located in the first section of the manual. The last two enhancementsprovide examples along with hand calculations for the facia design, detailing, and drawing.

Having received the program output on the facia you will want to check results to see that the output isas you would expect if you were to process the facia by hand.

1.4 6-99-2 Design of pulins/girts for faciaPROGRAM ENHANCEMENT

DATE: June 4, 1999

NUMBER: 6-99-2

PROGRAM: Roof Design

MANUAL: Design, Chapter 5

ENHANCEMENT: Design of pulins/girts for facia.

TO ACTIVATE: Currently active.

DESCRIPTION: Facia consists of a vertical or near vertical area which is offset from the buildingwall. The offset may be sufficient that there is another set of framing on a horizontal or nearhorizontal area. Possible girts on the vertical areas include those located on the top, bottom,intermediate, and a girt attached to the gutter. Possible purlins on the near horizontal areainclude roof purlins and soffit purlins. This enhancement describes the design of thepurlins/girts that are a part of the facia. From here on both the girts and the purlins will bereferred to as purlins.

A. CHANGES IN THE ROOF DESIGN INPUT FILE FOR FACIAThe following lines indicate the additions to the roof design input file to design facia. There isone line on deflection limits, two on facia size and location, one on purlins, one on panels, oneon bracing, and three on loading. Each of the terms are described in the help file for the roofdesign input file.

B. BRACING DESIGNThe extension bracing referenced above is in the plane of the near horizontal part of the facia.It is referenced by an extension Id and applies to eave extensions, facia, and canopy. Thebracing is designed for the seismic loads in the canopy, eave extension, and facia. Bracingdesign follows that used by the program for seismic loading in the roof of the building.

There is also bracing in the plane of the facia. This bracing is not designed, since it is only usedto provide vertical support for the dead load of the facia. Criteria for the use of this bracing isin the DS_FACIA file. The program enhancement on detailing facia describes the details ofbracing in the plane of the facia.

C. DESIGN OF PURLINS AND GIRTSThe above input line on facia purlins controls the design of the facia purlins and girts. Therecan be up to 6 different members. Member location is given on the right end of each linewhere: Roof = the eave strut member on the attachment beam, Soffit = the soffit member onthe attachment beam. Top = top of the facia arm, Interior = intermediate location along thefacia arm, Bottom = bottom location along the facia arm, and Gutter = a girt attached to the

MBS Facia Manual30


gutter and to the facia arm.

The purlin design is identical to that for roof purlins only the loads and deflection requirementsare unique for the facia. The basic extension loads are on line 35, deflection limits are on line 4,and the design load combinations are on line 39 and 40. An influencing factor in the purlindesign is the unbraced length of the compression flange. Criteria for setting the default valuesis detailed in the next section.

D. CONDITIONS FOR DEFAULT FLANGE BRACE SETTINGS FOR PURLINSOn the above data line, the program will list for each purlin the brace condition for each flange.This section describes the criteria that the program uses in making that setting. The optionsinclude: 'C' = continuously braced as provided by attachment to a screw down panel, 'Y' =braced at intervals not to exceed the spacings for screw down panels or standing seam panelsas entered in the DS_FACIA file, 'N' = no attachments to stabilize this flange. For thosepurlins that are attached to the facia arm, the blocking associated with diagonal bracingprovides a brace point for both flanges. If during building entry, the option for no sag straps isselected for roof purlins, the program will not use sag straps on the roof or soffit purlins. Sagstraps are not provided as an option with the facia purlins since there is no stabilizing memberon which to attach the sag strap.

The purlins are listed by location.

1.5 6-99-3 Design of facia beamsPROGRAM ENHANCEMENT

DATE: June 2, 1999

NUMBER: 6-99-3

PROGRAM: Component Design

MANUAL: Design, Chapter 5

ENHANCEMENT: Design of facia beams.

TO ACTIVATE: Currently active

DESCRIPTION: Facia arms are the vertical or near vertical members of the framing. They areconnected to the attachment beams which in turn is connected to the building frame. If theattachment beam also supports purlins and panels it will be designed the same as a sidewalleave extension beam or a canopy beam. In the absence of purlins or panels on the attachmentbeam, the beam is designed just to support the facia arm. This description is divided into manysections from overview to connection design.

A. OVERVIEWThe facia arms are designed in the design screen at the cell labeled 'CompDes' which meanscomponent design. First make the input file, edit the file if necessary, then make the output file.

The program will design a different facia arm for each different load width and beam type.The default load width for each interior beam is the sum of one-half the bay width for the bayson each side of the beam. The default load width for the end beams is one-half the adjacentbay width plus the extension at that end of the facia. Member types for individual beams canbe edited at the input file. If the facia extends beyond the bay line, a facia arm is designed asa simple span member at that location.

B. LOADINGEach facia beam is designed for three design loads: dead + collateral + live, dead + windpressure on facia + wind suction on the attachment beam, and dead + wind suction on thefacia beam + wind pressure on the attachment beam. The dead load and live load come fromthe facia entry data. Wind coefficients for wind load on the facia arm come from the buildingcodes. Most codes use +1.3 pressure and -1.3 for suction. Chapter 3 of the Design Manualdoes not report the facia wind load coefficient for each code. The program will default to windcoefficients of 1.3 until code dependent wind coefficients are provided.

C. ANALYSISThe facia arm and attachment beam are designed for the maximum internal actions that occurfrom the three design loads. The internal actions are calculated at the following locations: (a)facia arm design is at the intersection of the top of the attachment beam and the mid depth ofthe facia arm, (b) facia arm to attachment beam connection is at the intersection of the middepth of the facia arm and attachment beam, and 8 for the attachment beam design as well asthe connection between the attachment beam and the frame is at the intersection of the mid

PE: Design 33


depth of the attachment beam and the frame. Wind load and dead load are not applied to theattachment beam unless either roof panels or soffit panels are associated with the attachmentbeam.

D. FACIA ARM ALLOWABLE STRESSThe allowable shear, axial and bending stress are calculated according to the designated codefor hot or cold rolled members. For a flush intermediate purlin, both the top and bottom flangeshave unbraced lengths equal to the distance from the attachment point to the first flushintermediate purlin above the attachment point. If the intermediate purlin is only attached toone flange, the unbraced length for that flange is the distance to the that purlin. In the absenceof intermediate purlins the unbraced length is the distance from the attachment point to the toppurlin.

E. MEMBER SELECTION:The available facia beam members and corresponding data file are as follows:

Member: C R W OData File: DS_CCOL.SIZ DS_RCOL.SIZ DS_WCOL.SIZ DS_OCOL.SIZ

The 'O' member is an open C member and may be used for the attachment beam. As part ofthe facia input you select the member type. The program will select from all the members inthe data file unless you use the marker, @BEAM. When the marker is used, the program willselect from just the members that follow the marker and are before another marker or the endof the file.

F. MEMBER SELECTION: DEFLECTION LIMITSThe member deflection limits are set by the user as the facia data is entered. The programcalculates the deflection as the distance that the top end of the facia arm deflects from theconnection to the attachment arm. That is, the deflection is in reference to the attachmentpoint and not dependent on the movement of the attachment point. Similarly, the deflection ofthe end of the attachment beam is in reference to its attachment point to the frame.

G. CONNECTION OF FACIA ARM TO ATTACHMENT BEAMOptions for this connections are shown in Figure 11.4. The bolted end plate and weldedconnections are for R & W members. The 'B1' connection is for C & U members. The B1connection design is described on the attached sheet. For welded connections, the weld size isnot determined by the program.

H. CONNECTION OF ATTACHMENT BEAM TO FRAME MEMBERSThe attachment beam is connected to the frame members as referenced below:

The F E S options are the same as used in the other parts of the program and are described inSection 8.7.2 of the Design Manual. The LP connection was developed for eave extensionsand is described in PE 9-96-4. Design of connection options B1 to B4 are described in theattached pages titled "B1 to B4 CONNECTION DESIGN".

I. DESIGN REPORTS:There are two beam design reports, one for the attachment beam and one for the facia arm.The report format is the same as for the current eave extension beams.

J. CONNECTION DESIGN REPORTS:The type of connection report depends on the type of connection. For a lap connection and fora bolted end plate connection the report format is the same as the current report. The 'B2'connection report is in two sections, first the bolt data and then the connection plate date. Boltdata includes the actions at the connection along with the calculated maximum bolt force andthe allowable bolt force. Connection plate data includes: plate size, unbraced length, pluscalculated and allowable stresses.

1.6 6-99-4 Endwall column design with facia loading.PROGRAM ENHANCEMENT

DATE: June 15, 1999

NUMBER: 6-99-4

PROGRAM: Endwall Design

MANUAL: DESIGN

ENHANCEMENT: Endwall column design with facia loading.

DESCRIPTION: When the building has facia on endwall columns the program will design the endwallcolumns for both the building loads and the facia loads. This enhancement describes theprocess used by the program in the design of the endwall columns.

A. ADDED LINES TO THE INPUT FILEThe first line added to the input file has to do with endwall columns as shown below.

*(11)COLUMNS:* --Left_Corner-- -Right_Corner-- -Int_Facia-- Int_No_Facia Max_UnBr Base* Type Rot Depth Type Rot Depth Type Depth Type Depth Same Length Elev* (in) (in) (in) (in) Dep (ft) (in) 'R ' '-' 0.00 'R ' 'Y' 0.00 'R ' 0.00 'R ' 0.00 'Y' 30.0 0.00

The new items include reference to each corner column and to the corner column orientation.Also, there is a separate reference to interior columns with and without facia attached to thecolumn. The source of this data is the building input file, detailing method 86 on columnrotation, and line 4 of the facia file.

The following new data line provides information on the facia size and location. This is for thefacia on this endwall and the facia on the two adjacent sidewalls. The data source for this lineis the building entry.

Basic loads for the eave extension, canopy, and facia are listed in the following new line. Eachextension can have different loads. Dead load and live load are entered as a part of thebuilding facia data. The default collateral load is zero. Wind load on the extension beam is thebasic wind times wind coefficients from the particular building code. They are the same as isused for eave extension and for canopy. The wind load on the facia arm is taken as the basicwind times 1.3 as the wind coefficient for both wind pressure and wind suction.

B. ENDWALL COLUMN DESIGN LOADS

For most building codes, the endwall columns are designed for 6 design loads, as follows:

*(31)COLUMN & BRACING DESIGN LOADS:* No. Load Rafter_Wind Brace_Wind Column_Wind | Aux_Load*Load Id Dead Collat Live Left Right Left Right Press Suct Seis | Id Coef 6 1 1.00 1.00 1.00 .00 .00 .00 .00 .00 .00 .00 0 .00 2 1.00 .00 .50 .00 .00 1.00 .00 .00 1.00 .00 0 .00 3 1.00 .00 .50 .00 .00 .00 1.00 .00 1.00 .00 0 .00 4 1.00 .00 .00 .00 .00 .00 .00 1.00 .00 .00 0 .00 5 1.00 .00 .00 1.00 .00 .00 .00 .00 1.00 .00 0 .00 6 1.00 .00 .00 .00 1.00 .00 .00 .00 1.00 .00 0 .00

The column design is based on the wind load applied directly to the column and the concurrentaxial load in the column. The axial load is the reaction to the load on the roof surface. Thecolumn load is indicated as pressure or suction with the magnitude given in the 'WindPressure/Suction' line. Note that the design loads include a rafter wind and a bracing wind.These wind loads are equal to the basic wind times the wind coefficient for each buildingsurface. The wind coefficients are also listed in the input file. Loading 4 is necessary to obtaina breakdown of the basic load reactions given in the reaction report. Loadings 5 and 6 arenecessary to obtain the maximum uplift on the columns.

C. FACIA DESIGN LOADS

The combination of basic loads to make up the design loads for the facia will be the samecombination of loads that are used for the column design. Hence, for design load 1, the faciawill have dead load plus live load. Wind pressure and wind suction on the facia occur at thesame time as wind pressure and wind suction occur on the endwall column. For bracing windloads and rafter wind loads there are no wind loads on the facia.

D. EXAMPLE

Example 40 in the Example Manual illustrates the design of endwall columns for facia loading.

1.7 6-99-5 Design of rigid frames for facia loadingPROGRAM ENHANCEMENT

DATE: June 25, 1999

NUMBER: 6-99-5

PROGRAM: Rigid Frame Design

MANUAL: DESIGN

ENHANCEMENT: Design of rigid frames for facia loading.

DESCRIPTION: When a building has facia that is attached to the rigid frame, the program will designthe rigid frame for both the building loads and the loads on the facia. The method of framedesign is the same, with and without facia. The program change is in the automatic addition ofthe loads on the facia.

A. ADDED LINES TO THE INPUT FILEThe following three lines have been added to the input file.

*(15)SIDEWALL EXTENSIONS:*Surf No Ext -------Extension_Size------- ----Facia_Size---- Load* Id Ext Id Type Elev Width Slope Elev Height Slope Width 1 0 4 1 1 'FA' 14.500 3.000 0.0 13.500 6.000 0.00 25.00

*(16)EXTENSION LOADS:*Ext Dead Collat Live Wind1_Coeff Wind2_Coeff Facia_Wind*Id psf psf psf Left Right Left Right Left Right 1 3.00 0.00 100.00 -1.55 -1.55 -1.55 -1.55 -1.30 -1.30

The first line reports the size and type of extension while the second line is for the loads on theextension. The 'FA' extension type refers represents facia. When the building data includes afacia, the above two lines of data will be generated. The only exception is that in this case thelive load was edited to a larger value to recognize the accumulation of snow behind the facia.

The wind coefficients for 'Windl_Coeff' come from the building code and represent the windsuction on the horizontal projection of the facia. The 'Facia Wind' coefficients of 1.3 areindependent of building code since 1.3 is specified in some codes and most codes do notspecify the value. The user can edit any of the wind coefficients shown in the input file.

B. HOW ARE THE FACIA LOADS INCLUDED WITH THE BUILDING DESIGN ?Frame design loads are set in the 'Design Loads' section of the input file. Each design loadconsists of a linear combination of one or more basic loads. Basic loads include: dead, live,wind from left or right, and other loads. The loads from facia are included with the other basicloads in the frame design. For example, if the design load includes live load, then the live loadon the facia will be included. This same procedure is followed for the other basic loads.

C. HOW DO THE FACIA LOADS GET INTO THE FRAME DESIGN ?

MBS Facia Manual44


For each basic load the program calculates the reaction to the facia loads at the point wherethe facia attaches to the frame. These facia reactions are applied as concentrated loads on theframe at that same facia attachment point. Figure 8.2 in the Design Manual illustrates theapplication of concentrated design loads.

D. EXAMPLE SHOWING THE APPLICATION OF THE LOADS AND CHECKING THEBUILDING REACTION.The attached pages illustrate a building cross section where a facia is attached to the frontsidewall of the building. Following the building cross section there are four sections of handcalculations. The hand calculations are on each of four different loads. Each section shows thecalculation of the load and calculation of the frame reactions. The rigid frame design input filecan be edited to represent each of these loads. Then, the program will calculate the framereactions which can be compared to the hand calculations. The program generated framereactions are shown in brackets.

For this testing, you can remove the wind on the building by setting the building windcoefficients to zero. Similarly, you can set the building dead load and live load to zero. Whenyou set the building dead load to zero and include dead load as a design load, the building frameweight will be included. You can use hand calculations to remove the frame dead load fromthe program reactions.
