Hello,
I am using SAP2000 to create a grillage model for a multi-span bridge. The girders act as a composite section with the deck and, as a result, will have a different effective stiffness for positive and negative bending after cracking. Is it possible to incorporate this change in stiffness in the program (in other words, can I input specific section properties for positive and negative bending)?
Thank you in advance.
