DESIGN OF SIMPLE BEAM USING STAAD.PRO

AIM

To design a simple beam using STAAD.Pro

SOFTWARE USED

STAAD.Pro

PROCEDURE:

1) STARTING THE PROGRAM

1. Start STAAD.Pro by double clicking on the icon

2. Click New Project Tick “ Space” Add ‘File Name’ and choose location

Change Length Units to “Meter” and Force units “Kilo Newton” Click ‘Next’.

3. Tick “ Add Beam” Click ‘Finish’.

2) GENERATING THE MODEL GEOMETRY

4. Click on to View from +Z. [Can consider it as the Front view]

5. Draw the beam length using Snap Node.

3) SPECIFY MEMBER PROPERTIES

6. From the file menu go to

Commands Member property Prismatic Rectangle

YD = 0.45 m

ZD = 0.23 m

Click, Add Close

Click, Assign to view Assign Close

(Click ‘Yes’ when prompted to continue.)

4) SPECIFY SUPPORT TYPES

7. Commands Support specifications Fixed Click Add

Select support 2 Assign to view Assign

(Click ‘Yes’ when prompted to proceed)

5) SPECIFY MEMBER LOADS

8. Add self-weight and member loads.

Commands Loading Primary Load Give title (and type) Add

(1) To specify self-weight:

In the ‘Load & Definition’ window Click New Load items Self-weight

Then Assign each loads to the member.

Select the load Assign to view Assign Close

(Click ‘Yes’ when prompted to continue)

9. Scale the plotted beam loads as required. Goto toolbar

Scale Point Force (50), Dist.Force (25) ApplyOK

This will scale the length of the loads to eye view clarity.

10. Add Load values : Scale Labels Load values Apply OK.

11. Add Dimensions

Click Dimension Dimension to View Display Close

6) ANALYSIS

Analysis consists of three phases – Pre-Analysis, Analysis, Post Analysis

Start Analysing the beam

12. Pre-Analysis:

Commands Pre- Analysis Print Member Information To View OK.

13. Analysis:

Commands Analysis Perform Analysis

All or No Print OK.

14. Result Analysis:

Commands Post Analysis Analysis Results Yes OK

Commands Analyze Run Analysis

15. Results:

Mode Post processing Result view options Apply OK.

Click ‘Go to post processing mode’ Done.

7) STRUCTURE DIAGRAMS

16. View structure diagrams

View Structure diagrams Loads and Results Apply OK.

17. To get the various diagrams like SFD, BMD, etc.

Results View Values Beam results Ranges All

Go to the next tab – Beam Results Tick the required data Annotate

(You need to ON SFD and BMD or it will ask to ON automatically)

8) DESIGN

18. Go to Commands Design Concrete Design

Change ‘Current Code’ to ‘IS 456’

19. Click on Select parameters ( )

Click on symbol ‘<<’ Add necessary parameters like clear, Fc, Fymain, etc.

20. Click on Define Parameters ( )

Add values for each parameter as below

Clear = 0.03 m

Fc = 25000 kN/m2 (If mix is M25)

Fymain = 41500 kN/m2 (If steel bar used is Fe415)

If more parameters are added, give suitable values.

Note: Click ‘Add’ after each Close

21. Assign these parameters to the member

Select the parameter in ‘Concrete Design’ window Assign to view

22. Click on ‘Commands’ ( )

Add the required design requirements. Here we have a beam only. So we add two

terms. (1) DESIGN BEAM and (2) TAKE OFF.

23. Again come back to ‘Concrete Design’ window

Click on ‘DESIGN BEAM’ Assign to view Assign

24. Run Pre Analysis, Analysis, and Post Analysis again and the analyse the beam.

25. Analyze ‘Go to post processing mode’

26. Come back to ‘Modelling’ mode Double click the beam. It pop up a screen

showing various information about the beam.

Information includes Geometry, Property, Loading, Shear Bending, Deflection, Concrete

Design etc.

27. Print ‘Input File’

Go to File View Input Command file

Copy and paste input details to MS Word and print.

28. Print STAAD Analysis Output

Go to File View STAAD Analysis Output

Copy and paste to MS Word and print required details from it.

29. The printout of below items are taken care

(1) Loading Diagram

(2) SFD

(3) BMD

(4) Deflection Pattern

(5) Input file

(6) Concrete Take Off

(7) Concrete design

30. Design of the simple beam is completed.

RESULT

Analysis and design of a simple beam is done and the required structural drawings were

obtained using STAAD.Pro.
