- Abstract
- Over the last few years, a special purpose computer program, named 3D-BASIS, has been developed for the dynamic analysis of base isolated building structures. The program was described in NCEER Reports 89-0019 and 91-0005. In the 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 varification are presented herein. Also included in the report are the User's Guide (Appendix A), Input-Output printout of a case study considered in the report (Appendix B), and the source code (Appendix C) for easy reference.
