Here is a new idea!!

In this space we will publish brief technical content via interactive WebMedia and WebApps on the user-friendly and versatile Jupyter Notebooks.

Jupyter Notebooks are a great medium for interactive development and demonstration.

They are grouped into the following categories:

1. WebApps -- User friendly User Intefaces used to perform a specific task

2. WebDemos -- Documented scripts for proof/explanation of concepts

3. WebSamples -- Examples files to help you get started with fundamentals

4. OpenSeesScript -- Get started or get going with OpenSees right here!

Everyone is welcome to submit content! Please contact me.

WebApp

Use this WebApp to perform an Elastic Frame Analysis using OpenSeesPy

Developer: Silvia Mazzoni, May 2021 

WebDemo

This notebook describes the elastic frame buckling computations developed by Luigi Caglio.
The original idea was posted as a reply to a post in the OpenSees Facebook group and the steps were then summarized in this blog post.

This is a great example where you learn how to define a section and perform a moment-curvature analysis on this section. Both a uniaxial and a fiber section are shown in this two-part example

My first link to someone else's GitHub Repository!

This is a great place to get started with computing response spectra!

This Notebook computes the response spectra for a ground motion at various damping ratios.

OpenSeesScript

This is an OpenSeesPy simulation of one of the numerical examples in A robust composite time integration scheme for snap-through problems by Yenny Chandra et. al. It's a special problem involving dynamic snap-through with large deformations in elastic range. In their study, a new three sub-step composite time integration algorithm was presented to handle such problems

OpenSeesScript

This is an OpenSeesPy simulation of one of the numerical examples in a previously published paper. The Core was purely written in Mathematica. This is an attempt to perform the analysis again via Opensees Core, to see if you can get the similar results.

OpenSeesScript

This is an OpenSeesPy simulation of a simple linear 3 DOF system introduced by Bathe and Noh. The model was used to demonstrate the ability of Bathe method in filtering out the unwanted artificial high-frequency responses. The effectiveness of numerical dissipation in a specific time integration algorithm could be evaluated by analyzing this benchmark model problem.
