摘要: 本文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创建了钢筋类、混凝土类、梁和柱类,建立了一套能模拟框架房屋地震倒塌过程的计算机仿真模型。结合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多媒体视景系统,用户可交互式地输入参数,利用该系统对钢筋混凝土框架结构房屋地震倒塌的机理做了研究。仿真实例表明该系统能较好地反映实际框架结构的地震倒塌过程。Abstract: Based on the characteristics of reinforced concrete frame structures. object-oriented theory is used to model reinforcement, concrete, beam and column A computer simulation model is presented to simulate frame collapse during earthquake. Computer visualization and multimedia system are integrated to create a multimedia simulation system Users can input parameters by interactive interface. The collapse of RC frame structure during earthquake is studied by the simulation system. It is shown that the system can simulate practical frame structure in the earthquake collapse process correctly.
