基于震害的钢筋混凝土框架结构倒塌机理的集成多媒体仿真研究
|
摘要
本文在总结历次实际地震震害特点的基础上，针对钢筋混凝土框架结构的特点，运用面向对象的建模理论建立了一套能模拟房屋倒塌过程的计算机模型，结合钢筋混凝土框架三维非线性动力有限元方法，给出了一种计算机能自动判断局部或整体可动机构的快速算法，并引入可视化技术及多媒体系统集成原理，开发了框架倒塌仿真的集成多媒体仿真系统，对钢筋混凝土框架结构房屋的倒塌机理作了研究，仿真实例表明该系统能较好地再现框架的倒塌过程。
Based on the summary of several earthquake disasters, a computer model is presented to simulate collapse course by objected-oriented method in accordance with the characteristics of reinforced concrete frame structure. A quick algorithm is given for computer to judge structural failure mechanism automatically in a 3-D nonlinear RC dynamic FE method. Also computer visualization and multimedia system integration is introduced to create a RC frame structure's collapse simulation system. An example shows that this system can simulate practical collapse course correctly.
