面向对象方法实现混凝土框架推覆试验

Simulation of Reinforced Concrete Frame Pushover Test Based on the Object-oriented Programming Method

弹塑性静力分析方法(即Pushover分析法)正逐步成为一种分析结构地震性能的新方法,它既避免了以往非线性动力分析的繁琐,又具有较好的准确性。但目前针对Pushover试验进行分析的软件很少。文章对钢筋混凝土框架的Pushover试验理论进行了研究,利用面向对象的方法实现了混凝土框架虚拟建模、荷载施加、传感器安装以及最终数值分析的Push-over静力试验全过程。文章中给出了实现混凝土框架Pushover试验软件的总体编制思想及实现方法。

Inelastic static push - over method is becoming a novel methodology for seismic evaluation of structures. It＇s been proved by practical engineering abroad as having good accuracy and simplicity. It can save both the cost and computational time. But . there is little software aiming at solving the problem of Pushover test now. In this paper, the software is programmed with object - oriented method, which can simulate actually the whole process of reinforced concrete frame push over test by studying the method of Pushover analysis. The core of program idea and the way for its realization are also presented.
