Hi all, I would like to model a mixed steel concrete beam, using a forcebeam column element for the steel beam and a shell element for the concrete slab. After that I would like to connect the two elements with rigid links and zero length elements to simulate the presence of a connection. What mater...

Hello to all, I would like to know if by modeling a structure with different fiber discretizations, or using the patch fiber command or using the fiber command, there are differences in the results? If yes, in which cases is it useful to discretize with quadrangular fibers and in which cases with tr...

Hi,

Loadconst -time 0.0
But the pushover doesn't start from zero but start from 1. The Timeseries is Linear . Can you help me? Thanks

Hi, I have modelled a 3d structure with STKO and after I have modified .tcl file manually. I have a question: I have modelled Ipe550 section with STKO triangular fiber and I got a different result compared to the case in which the same section has modelled with quad patch model (writing manually sec...
