In some models we need to apply imperfection to the model or part of it. One of these cases is when we conduct push over (monotonic or cyclic) analysis on braced frames.
In these videos you will learn how to model a steel braced frame in ABAQUS FEM software and how to apply imperfection using mode shapes and conduct cyclic loading analysis . 👇👇👇

👉opsanalyze Version 1.2:
opsanalyze is a python package to perform different kinds of analysis on opensees models. This program, automatically adjusts displacement/time increments according to the convergence of the solution in pushover (monotonic and cyclic) and transient analysis. In addition, this program has a function to apply damping to the structure or part of it. The region in which damping will be applied is defined by specifying x, y and z limits inside the domain. Program automatically determines the elements and nodes inside the specific region and calculates mass and stiffness coefficients and applies damping using region or rayleigh command.
