Three Acts with the Two Node Link

This post follows three-act structure in verifying the flexural and shear response of the TwoNodeLinkSection element. Setup I’ve been working on the TwoNodeLinkSection element, which is like a TwoNodeLink, but uses a section object instead of multiple uniaxial materials. Basically the same spin the ZeroLengthSection puts on the ZeroLength element. Using a section object inside a two … Continue reading Three Acts with the Two Node Link →

A Simple Base-Isolated Model

Although there are several base isolator elements available in OpenSees, I don't know much about base isolation. And when I don't know much about a topic, I look for a simple example to play with--usually something elastic that can be expanded later and that I can return to when I run into issues with nonlinear … Continue reading A Simple Base-Isolated Model →
