本文将钢筋混凝土结构的理论分析方法和专家知识相结合,研制了钢筋混凝土结构破坏过程的模拟仿真系统。该系统包括三个模块:输入数据模块。可以自动生成网格;分析判断模块,包括非线性有限元分析和智能判断:图形显示模块,可将位移、应力、裂缝用图形显示出来。运用本系统对有实验结果的简支梁和三维带孔钢筋混凝土结构进行了逐级加载模拟分析,分析结果与实测相当接近。
This paper combines the theoretical analysis methods and expert knowledge of reinforced concrete structures, and develops a simulation system for the failure process of reinforced concrete structures. The system consists of three modules: the input data module. The grid can be automatically generated; the analysis and judgment module includes nonlinear finite element analysis and intelligent judgment: a graphic display module, which can display the displacement, stress, and cracks graphically. Using this system, the load-supported beams and three-dimensional reinforced concrete structures with holes were simulated by step-by-step loading analysis. The results of the analysis are close to the actual measurements.
