Thanks for your suggestions. I am still having difficulty. Please see the attached pdf. Typically, when calculating your standard strong axis and weak axis moments of inertia for a transformed section, you divide the effective slab width by the modular ratio and calculate everything...
Thank you for your response! Actually, what I am trying to do is model a bridge superstructure in STAAD for a long term composite section (3n) for my bridge barrier (DL2) loading. In speaking with Bentley, STAAD cannot handle a transformed section based on 3n and can only look at a short term...
Can anyone tell me how to calculate the warping constant for a composite plate girder? The formula for the girder itself is from AASHTO C6.9.4.1.3-1. However, how do I account for the transformed slab?
