In collaboration with the University of California, Berkeley, Version 1 of the program SASSI2010 is now available. The new version offers many enhanced features including capabilities for analyzing very large models on desktop computers, capabilities for ground motion incoherency analysis, random vibration theory for seismic analysis avoiding time history as input, windows based graphic user interface for data processing, execution and post processing and plotting of SASSI results with a unique plotting program to plot all or parts of the SASSI finite element model. Additional information on details of SASSI2010 and its enhancement from previous SASSI2000 version is available upon request.
