How can I efficiently reduce section properties for all superstructure frame elements created by the bridge modeler?
Extended Question: For my particular model, the Bridge Modeler generates hundreds frame sections since the superstructure is highly curved and the cross-section varies. If I want to reduce the moment of inertia of the superstructure (cracked concrete, Icr = 0.5 Ig, Jcr = 0.05 J), do I need to go to Section “Property > Frame Properties” and set modifiers one by one? This is lots of work and very inefficient, I was wondering if there’s any easier way to model the cracked concrete for the superstructure. Answer: There are several ways you can efficiently assign reduced sectional properties for the superstructure members. For example, you could follow the procedure described below: • Define a group that will contain all superstructure frame elements. Such group can be defined directly on the “Bridge Object Data” form via the “Staged Construction Groups” assignment. • Define frame property modifier to be used via “Define > Name Property Sets > Frame Modifiers” menu command. • Define staged
