Check out the new H5DRM load pattern for DRM-based seismic analysis on OpenSees. You can find the documentation and all the example files here.

DRM stands for the Domain Reduction Method. It is a game-changer for seismic analysis. The DRM allows the analyst to subject their soil-structure systems to earthquake input featuring rich 3D motions. That is, you're no-longer restricted to assuming that the in-coming seismic wave-field is a planar wave, which is what 99% of analysis nowadays still assume. This is very important for several types of structures, for example as I showed was true for nuclear power plants subjected to near-field earthquake motions.
