In a two span steel composite bridge, how can I account for the cracked section properties over the pier? I am not using the design function, but I need to reduce the section properties in the cracked regions to properly model the deck's stiffness.
Answer:
You can account for the cracked section properties by reducing the section stiffness. You can do this from Properties >> Section Manager >> Stiffness, or from Load >> Construction Stages >> Composite Section for Construction Stage if you are using construction Stages. You can find information on these functions and how to define the parameters in the Online Manual.
Section Manager:
Composite Section for Construction Stages:
