Hello everyone,
I am working for one of the underground metro projects where I have to design various slabs. These slabs have to be designed for bending moment, torsion and shear force for large number of load combinations. The practice which I am following is to create a STAAD model and obtain various sectional forces from STAAD for design and doing the design part using customized excel spreadsheet which I have developed.
STAAD provides bending moment contours/ result tables and torsion contours/ result tables separately and doesn’t add as per Wood and Armer method (which we normally follow in practice) for any particular load combination. And yes, STAAD design includes torsion with bending moments in ULS case but I have to do stress check as well as crack width check so it’s not of much use to me. It is very cumbersome process where I have to add absolute value of torsion with bending moment for large number of load cases (Wood and Armer method) which I want to avoid. I wish if someone can suggest a simpler way. Also, is it possible to develop a macro using OpenSTAAD.
Regards,
Ankit Gupta
