3D-BASIS-TABS Version 2.0: Computer Program for Nonlinear Dynamic Analysis of Three Dimensional Base Isolated Structures

Keywords: 3D-BASIS-TABS, Nonlinear Dynamic Analysis, Base Isolated Structures, Three-Dimensional Analysis, and Computer Program.

Abstract: This report describes the development of computer program 3D-BASIS-TABS, Version 2.0. The new program is an enhanced version of 3D-BASIS-TABS. The report should be viewed as a continuation and addition to previous reports NCEER-93-0011 and NCEER-91-0005. The enhancements that are documented in this report include: 1) addition of new isolation elements; 2) models of nonlinear dampers and other hysteretic elements; 3) additional verification; 4) addition of several new example problems; 5) new input/output format for easier usage; and 6) updated user's manual.
