Computer Program for Inelastic Analysis of 3-Dimensional Reinforced-Concrete and Steel Seismic Buildings

摘要

A user's guide for the computer program, INRESB-3D-SUP, for analyzing elastic and inelastic building systems subjected to static loadings, multicomponent earthquake motions, and psudo-static cyclic loadings is presented. The program also calculates natural frequencies and buckling loads. The report includes the program listing, a description of the program, instructions for data preparation, and a guide to modify the program's dynamic storage. The structural members may be elastic 3D prismatic beams, nonlinear reinforced concrete shear walls, and nonlinear springs. The Cheng-Mertz hysteresis models are for bending, shear and axial forc-deformation relationships of low-rise walls. The Takeda model may be used for beams, columns and slender walls. The bilinear hysteresis model and thegeometric matrix for large deformations are also available. The computer program has been developed for efficient computation and data preparation.
