摘　　要：对河海大学土木工程学院研制的有限元计算程序的前后处理部分进行了完善,用面向对象编程语言VB开发了钢筋混凝土平面非线性有限元可视化系统.该系统采用图形用户界面,前、后处理结果全部用彩色图形显示,分析简单直观.通过与理论及实验都很完善的简支梁在不同配筋和受力情况下的受力全过程进行对比,进一步验证了该软件计算的可靠性和图形的准确性.该软件可用于多种混凝土构件或结构受力全过程分析,其非线性阶段仿真分析的可靠性尤其突出.Based on the improvement of the finite element program in the pre-processing and post-processing parts developed by College of Civil Engineering of Hohai University, a visualized system for nonlinear finite element calculation of reinforced concrete was developed by use of the object-oriented software VB. With the graphical user’s interface, the results of pre-processing and post-processing are demonstrated with color graphs, which makes it easy for the program to be used. By a comparative analysis of the full stress process of simply-supported beams under different reinforcements, the reliability of the program and the accuracy of graphs were verified. The improved program can be used for full process analysis of various concrete components and structures, especially for their nonlinear phases.
