Introduction

Thank you for your purchase of STAAD Foundation Advanced . STAAD Foundation Advanced is anexhaustive analysis, design, and drafting solution for a variety of foundations. These include generalfoundation types such as isolated, combined footings, mat foundations, pile caps, slab on grade, and slabon piles as well as plant foundation such as vertical vessel and heat exchanger foundations. A part of theSTAAD family of products, STAAD Foundation Advanced can automatically import and update thegeometry, loads, and reactions from a STAAD.Pro model and then accurately design isolated, pile cap,combined footing, mat foundations, and even perform pile arrangements for a pile cap. Spreadsheetdata (e.g., such as that in Microsoft Office Excel) can be copied and then pasted in STAAD FoundationAdvanced, increasing the efficiency and versatility of the program.STAAD Foundation Advanced not only analyzes and designs a myriad of foundation configurations, butwill also produce production quality reports and detailed 3D rendering of your foundation structures. Italso produces site-ready construction documents such as: detail drawings, general arrangementdrawings, and schedule drawings. With full OpenGL graphics, engineers can clearly see the displacedshape, stress distribution, reinforcement layout, and force diagrams of their supporting structure. Allmodels use physical objects including physical beams, physical slabs, automatic meshing, loaddistributions, and support generation. STAAD Foundation Advanced designs the physical slabs ratherthan individual elements.For mat foundation designs, STAAD Foundation Advanced utilizes a true finite element design using theindividual element stresses rather than using column strips. STAAD Foundation Advanced can be usedin a stand-alone mode or can be used in conjunction with STAAD.Pro where the support reactions fromthe main model and associated load cases are automatically brought in.Because STAAD Foundation Advanced provides a total solution for your foundation needs, a built-inproject management system enables line and span of control, revision records and multi-jobfunctionalities. This helps you reduce cost in assembling the technical and managerial information foryour foundation. Full step-by-step calculations are also provided in XML form to verify each and everyoutput provided by the program. These verification checks can be easily shared with your clients forapproval.Also, the calculation sheets can be customized according user specification and entire foundationreporting can be standardized.We hope you enjoy your experience with STAAD Foundation Advanced. If you have any questions orproblems with the program, please visit our product page at http://www.bentley.com/Staad.foundation.

1.2 General ModeThe following features have been added to the General foundation mode in STAAD FoundationAdvanced v7.

Machine Foundation Wizard

STAAD Foundation Advanced v7 can parametrically create, analyze, and design foundations forvibratory machinery per ACI 351.3R-04 using a new wizard feature. The program uses the STAAD.Proengine for dynamic analysis and produces state-of-the-art reporting with dynamic graphs embedded inthe calculation sheet.Rotating and reciprocating machinery is common in production plant facilities and these devicestypically require uninterrupted use. Downtime in these heavy machines can be very costly and thusdesigning machine foundations within permissible operating limits of this type of machinery is critical.These machines cause dynamic forces and vibrations and excessive vibrations are detrimental to themachinery, supporting foundations, and any operating personnel.The STAAD Foundation Advanced vibrating machine feature is capable of taking values provided bymechanical and geotechnical engineers for machine loads and soil parameters, respectively. Alternately,machine load and soil spring properties can be calculated based on the equations provided in ACI351.3R-04.Single, combined, and combined with gearbox block foundation configurations can be designed usingthe wizard.A dynamic analysis is performed with analysis parameters specified by the engineer using theSTAAD.Pro analysis engine.

ReportingSTAAD Foundation Advanced v7 includes state-of-the-art reporting for vibrating machine foundationsin the calculations sheet. Along with repeating the input values (for validation), detailed calculations forload generation, soil spring generation, mode shape results, frequency check, and vibration amplitudecheck per ACI 351.3R-04. The calculated values for supported machinery are plotted on ACI 351.3R-04Figures 3.9, 3.10, and 3.11 in the calculations.

Tank foundation design complies to:• ASCE 7• ACI 318• PIP (Process Industry Practices) STE03350• Seismic loads per API 650, Section E• IS 456 and IS 875 Part 3

V8i (Release 6)Plant Mode


Drilled/Driven Pier foundations

A new parametric wizard has been added to design drilled shaft or driven pier foundations used toresist axial and lateral loads. The pier can have any number of sections along its length and essentiallyany number of soil layers can be modeled.

Group Horizontal Vessel Footings

The foundations at each end of a Heat Exchanger/Horizontal Vessel foundation can be designed asidentical. This option will then only allow input for the "Left" Footing and design both foundations forthe maximum requirements.Simply set the Identical Footings option on the Footing Geometry page when Isolated Footings arebeing designed.

Self Weight for Ultimate Loads

The option to include the foundation self weight for ultimate loads (concrete design) under the GlobalSettings dialog box is now respected for Plant foundation jobs as well as foundation jobs created underthe General foundation mode.Simply click the Global Options tool found on the Home ribbon tab and set the option.

4.3 General ModeThe following features have been added to the General foundation mode in STAAD FoundationAdvanced:

V8i (Release 6)General Mode


Octagonal Footing

An isolated, octagonal footing—similar to the option for the Vertical Vessel in Plant mode—can bedesigned as a separate foundation job from the General mode. Parameters similar to other isolatedfootings are entered via property pane, as well as anchor bolt data for concrete design.This foundation types can be selected when creating a new foundation job in the General mode for UScode design.

Strap Footing

A strap footing—similar to the option for Heat Exchanger/Horizontal Vessel in Plant mode—can bedesigned as a separate foundation job in the General mode. This foundation type consists of a gradebeam between two isolated footings. This single job analyzes the beam and footing system and designsboth elements.This foundation types can be selected when creating a new foundation job in the General mode for UScode design.

Australian Code Modification

Several enhancements have been made to the design of foundations per the Australian code:• Strength reduction factor, φ, from table 2.3: one-way shear, punching shear, and reinforcement• Modified punching shear calculations per Sect. 9.2• Refined minimum percent of steel• A revised calculation sheet
