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。 In this paper, based on the characteristics of the previous earthquake and the characteristics of the reinforced concrete frame structure, a set of computer model that can simulate the process of house collapse is established by using the object-oriented modeling theory. Combined with the three-dimensional nonlinear dynamic limited Element method, a fast algorithm for computer to automatically judge partial or whole movable mechanism is given. By introducing the visualization technology and the principle of multimedia system integration, an integrated multimedia simulation system of frame collapse simulation is developed. For reinforced concrete frame structure houses The collapse mechanism is studied. The simulation results show that the system can reproduce the collapse of the frame well.
