| 摘 要： | 在M SC.M arc有限元分析软件程序的基础上,开发了针对钢筋混凝土杆系结构的钢筋混凝土纤维模型程序THU F IBER。在该程序中,结构构件中的混凝土和钢筋分别用不同的纤维来模拟,从而使得材料滞回特性得到较准确的表达。为了验证本程序的计算能力,本文针对一个钢筋混凝土高层框架结构进行了静力弹塑性分析和动力时程分析,结果表明,THU F IBER具有出色的分析非线性问题的能力,可以进行结构倒塌模拟。

| Abstract: | 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. |
