General property cross sections

Post by msavor »

Hello,
I have a question regarding cross sections. Is there any option to assign cross section of general properties (e.g. I manually assign stiffness, E...)?
I am doing a model of bridge which has different cross sections than specified in seismostruct, but their dimensioning is not of interest to me. I need them for the global stiffness, but I don't know how to model them.

Dear Marta,
if you need to use an elastic element, you can directly specify custom values of EA, EI2, EI3 and GJ (refer to the HelpSystem -> Element Classes -> Elastic frame element).
