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

2. 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)  ApplyOK
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

3. 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)

4. 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.

5. 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

6. 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.

7. Information includes Geometry, Property, Loading, Shear Bending, Deflection, Concrete
Design etc.

8. 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.

9. 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.
