Abstract: Over the last few years, a special purpose computer program, 3D-BASIS, has been developed for the dynamic analysis of base isolated building structures. This program was described in NCEER reports 89-0019 and 91-0005. In this report, 3D-BASIS is extended to the case of multiple buildings with a common isolation basemat, while retaining other features of 3D-BASIS. The program is called 3D-BASIS-M and its development and verification are presented herein. Also included in this report are the User's Guide, Input-Output printout of a case study considered in the report, and the source code for easy reference.
