This example demonstrates how to use the viscous damper material within a simple single story shear frame.

A plane cantilever column is shaken by an earthquake. Material nonlinearity is accounted for using the force formulation and fiber-discretized cross sections

Integration of an inelastic single-degree-of-freedom (SDOF) system.

Corotational frame elements are used to approximate Euler's buckling load.

This example demonstrates how to perform eigenvalue analysis and plot mode shapes.

This code computes the RotD50 Sa and RotD100 Sa Spectra of bi-directional ground motion records. spectra.py The source code for this problem is adapted from the example by Jawad Fayaz at https://openseespydoc.readthedocs.io/en/latest/src/exampleRotDSpectra.html  .

Basic sensitivity analysis is performed

Double-Layer Shallow Dome   March 2020, Amir Hossein Namadchi   This is an OpenSeesPy simulation of one of the numerical examples in our previously published paper  . The Core was purely written in Mathematica. This is my attempt to perform the analysis again via Opensees Core, to see if I can get the similar results. In the paper, we used Total Lagrangian framework to model the structure. Unfortunately, OpenSees does not include this framework, so, alternatively, I will use Corotational truss element....
