IDARC 2D

A Computer Program for Seismic Inelastic Structural Analysis

Developed at the State University of New York at Buffalo, IDARC was first introduced in 1987 for the purpose of analyzing earthquake damage in multistory, reinforced concrete buildings. Since then, numerous enhancements have been added, including the ability to analyze a wide variety of structures, structural materials, and, most recently, structural damping devices. New features are continuously being added to IDARC, while three dimensional and bridge specific versions are currently being developed.

The program is distributed free, with corrections and minor updates, as part of a Membership in a Users Group. For information on membership check the appropriate button above. Non-members can also get a version of the program executable free without any support.
