5. History of STAAD.Pro
 STAAD Pro was originally Developed by
Research Engineers International in Yorba
Linda, CA
 In late 2005, Research Engineer International
was bought by Bentley Systems.

6. Introduction to STAAD.Pro
 STAAD.Pro is a Structural Analysis Design Program
Software.
 It is used for 3D generation, analysis and multi-material
design.
 It’s a limit state method concept.
 It will create a framed structure only.
 This is the one and only structural engineering software.
 BEAVA – Bridge Engineering Automatic Vehicle Application

7. STRUCTURE
It’s Combination of Structural Element
1.Slab
2.Beam
3.Column
4.Footing

8. Solid Modeling
Stair Case Water Tank
Shear wall

9. Units
Length : Meter & Millimeter
Force : Kilo Newton & Newton
Load – KN/m Fc & Fe – N/mm2

10. STRUCTURE
 Real model – structural element .
 Physical model – modeling software .
 Mathematical model – STAAD pro design.
STRUCTURAL

11. Framed Structure : ( G+2 & above)
This Structure having the combination of
Beam, Column and Slab to resist the lateral and
gravity loads.
BASED ON LOADING
Load Bearing Structure : ( G+2 )
This Structure instead of
column and Beam, it has walls
taking the load.

15. Concrete : ( Fc - Compressive Stress)

16. Steel : ( fy - Tensile Stress)
Mild Steel – Fe 250
High Yield Strength Deformed Bars :
– Fe 415 & Fe 500
TMT – Thermo Mechanically Treated:
The TMT bars have a hard outer surface and a
softer core. Their manufacturing process includes hot
rolled steel wires passed through water
