In this OpenSeesPy Crash Course video we take a first look at OpenSeesPy a Python library for structural analysis.

OpenSeesPy is packed with functionality and can handle, linear, nonlinear, static and dynamic analysis of structures.

There is a full writeup of this tutorial on the EngineeringSkills website here…

⬇ You can also download the code directly from the tutorial page.

In this video we get started with a simple 2D truss analysis. We’ll analyse a structure that we covered previously in our Direct Stiffness Method Truss Analysis course and confirm our OpenSeesPy analysis against our previous model output.

This should be enough to get you started with OpenSeesPy once you’ve finished this tutorial, five into the library. It has ALOT to offer.
