cores + Flat slabs + Raft

Modeling .. All in one system

STRAP For RC Designers

Special Features for Shear Wall Modeling

Any complicated shear

wall/ lift core section can

be defined in single step

Automatic generation of rigid links

for efficient load transfer

Program automatically generates additional beams, where ever

coupling beams are defined for proper moment transfer

STRAP For RC Designers

➢ Possibility to define opening in the shear wall

➢ Automatic creation of nodes when wall section changes

➢ Change the wall section by moving the node in the main geometry

Special Features for Shear Wall Modeling

STRAP For RC Designers

FE Modeling is very SimpleUser controlled

existing nodes

Automatically aligns with

adjacent elements

STRAP For RC Designers

Beam design and detailing

Reinforcement for beams for

the moment at the face of

the column. Considerable

savings on reinforcement.

Program automatically

detects continuous beams

Cost effective designs

STRAP For RC Designers

Automatic Calculation

of effective length factors

Automatic

Detection of un supported

lengths for column design.

Automatic detection unsupported lengths

STRAP For RC Designers

RC Column Design features

➢Design for any shaped cross sections

➢Automatic Optimization of reinforcement

for a given cross section.

➢The column capacity calculation is exact.

Program calculates neutral axis and stress

& strain in each bar from neutral axis.

➢Reinforcement can be grouped for different

levels and different columns.

➢Graphical Display of reinforcement and column

capacity factor.

User can specify the

reinforcement in the

column

STRAP For RC Designers

Reinforcement can be changed after

detailing. The program automatically

checks for codal provisions.

codes are available.

In addition to that

user can add their

own shape codes.

Automatic scheduling &

quantity calculation

STRAP For Steel Designers

Steel Design/Optimization

If you are serious in designing Least Cost Steel

Structures then STRAP is the best choice for you.

STRAP For Steel Designers

➢ The shapes can be arbitrary combinations of standard steel sections, plates and sections defined by dimensions.

➢ Above arbitrary shape can be designed in steel post processor

User defined steel section shapes

STRAP For Steel Designers

➢ Slender sections can be designed as per Indian code

➢ Design of castellated and cellular beams

➢ Spilt beam with tapered section. Program automatically creates new sections at the new intermediate nodes for a tapered beam

Design of slender sections

STRAP For Steel Designers

Automatic Calculation

of unsupported lengths

Design of single/ star

angles about principal

axis.

Automatic detection unsupported lengths

STRAP For Steel Designers

COMPOSITE SECTIONS

➢Calculation of shear studs

➢Partial shear connection

➢Design for wet concrete condition

➢Calculation of short term and long

term deflections

➢Option to account for negative

moment reinforcementComposite column

and beam design

Analysis and design of composite columns and beams

For Transmission Tower Designers

➢IS 802 is available for tower design

➢Automatic generation of wind load on towers/ Open

structures.

➢Different cost factors can be assigned to various section

types or member groups.

➢Selection of sections can be subject to user constraints.

Specify the deflection or drift, program automatically

optimizes the whole structure

- Engineer can get the least cost structure using STRAP!!!

For Cost Optimization

STRAP For Steel Designers

STRAP For Steel Designers

Automatic GA drawing preparation and quantity

calculations.

Export through DXF

to any cad programs.

STRAP For Steel Designers

Automatic design of steel connections

➢ Beam to beam

➢ Column web to Beam

➢ Column Flange to Beam

➢ Column base plate design

➢ Design for AISC, BS & Euro Code

STRAP For Steel Designers

➢Design for AISI, BS and Euro codes

➢New section types can be added to the

library by defining the basic dimensions only.

➢Calculation of torsional flexural buckling for

LTB

➢Design for reduced section according to the

web thickness/depth ratio

➢Hot rolled sections can be used in the same

model.

➢To define new sections apart from standard,

CROSEC module is necessary.

For Cold Formed Steel DesignersStandard Sections + user can create customized sections

We recommend

STRAP + Cold formed+ CROSEC for cold formed steel

designers

Simple to most complicated sections can be

analyzed and designed.

➢Appendix A - "Calculation of minimum

reinforcement, crack spacing and crack widths in

relation to temperature and moisture effects“

➢Appendix B - "Calculation of crack widths in

mature concrete“ - The program calculates the

reinforcement required to satisfy moment/

force requirements

STRAP For Water retaining structures

➢ Automatic calculation of nodal weights

➢ Simple to define rigid diaphragm actions

➢ Inbuilt response spectra for various damping ratios

➢ Possibility to use site spectra

➢ Automatic scaling of response spectrum results

➢ Option to define eccentricities at various levels

➢ Assign to the CQC the signs of the results calculated for the dominant mode shape

STRAP Earthquake Analysis

➢ The storey drift in any storey shall not exceed 0.004 times the storey height

STRAP Earthquake AnalysisStorey drift calculations

STRAP 2012 – New features

➢ Program will list centre of mass and centre of rigidity for each floor.

STRAP Earthquake AnalysisRigidity & mass centre

Storey Shear & Moments

STRAP Earthquake Analysis

Stability coefficient (Theta)➢ P-Delta effects on story shears and moments are not

required to be considered where the stability coefficient (Theta ) is equal to or less than 0.10"

STRAP Earthquake Analysis

Weak Stories Calculation➢ A weak storey is one in which the storey lateral

strength is less than 80% of that in the storey above

STRAP Earthquake Analysis

Soft Storey Calculation➢ A soft storey is one in which the lateral stiffness is less than

70% of that in the storey above or less than 80% of the average lateral stiffness of the three storeys above

➢ the columns and beams of the soft storey are to be designed for 2.5 times the storey shears and moments calculated under seismic loads
