Dear all.
Iam trying to model a Steel open box girder section with a concrete deck slab in NASTRAN. I need to perform Nonlinear analysis for the Box girder.
We are aware that Modulus of concrete in P-Delta behavior and M-Phi behaviour are different. From this prespective please let me know what Modulus and Thickness of deck slab i need to use to get my Nonlinear results properly.
Do i have to use any Effective modulus and effective thickness for concrete deck slab? In which case how do i compute them?
Thanks in adv
