Collapse Simulation of High-Rise Structure of Concrete under the Action of Static and Dynamic Load

Based on program of MSC.Marc finite element analysis software,a program THUFIBER for fiber model of pole system structure of ferroconcrete is developed.In the program,concrete and rebar in component of construction are simulated separately by different fibers,expressing more accurately hysteretic property of material.In order to test calculation ability of the program,static elastic-plasticity analysis and dynamic time history analysis on a high-rise frame structure of reinforced concrete are carried out by using this program in the paper.The result indicates that THUFIBER has remarkable ability to analyze nonlinear problems and can simulate collapse of structure.
