INRESB-3D: A Computer Program for Inelastic Analysis of Reinforced-Concrete Steel Buildings Subjected to 3-Dimensional Ground Motions. Report No. 2

摘要

This report is a user's guide for the computer program, INRESB-3D, for analyzing elastic and inelastic building systems subjected to the simultaneous input of static loads and multicomponent earthquake motions, which can be applied in any direction of the structural plane. The building systems may have elevator cores, floor diaphragms, and shear walls of reinforced concrete, as well as beams, columns, and bracings. The computer program has been developed to achieve efficiency in both computation and data preparation. The output solutions include the static results of member forces and nodal displacements, as well as the dynamic results of member forces, nodal displacements, ductility factors, excursion ratios, seismic input energies, dissipated energies, and the options of plotting some of the dynamic results. The report includes the program list, a description of the program, instructions for data preparation, and a guide to modify the program's capacity.
