Hello.

I would like to create a rectangular concrete-filled steel tube (CFST) structure in the software. This requires defining a hollow concrete section. How should this be implemented in the software?

Also, is it necessary to define contact interaction between the steel shell and the concrete, similar to what is done in Abaqus?

Unfortunately, SeismoBuild v2026 does not support concrete-filled steel tube members. Composite members will be introduced in a future version of the program.
