钢筋混凝土构件正截面强度计算的OOP方法
|
摘要
本文提出一种在ＯＯＰ（Ｏｂｊｅｃｔ－ｏｒｉｅｎｔｅｄ Ｐｒｏｇｒａｍｍｉｎｇ：面向对象程序设计）环境中采用数值积分和非线性方程组数值解的方法进行钢筋混凝土构件正截面极限承载力计算和配筋设计的计算机方法。所有基于平截面假定并以边缘混凝土达到极限压应变为破坏标志的极限状态设计原则的正截面强度计算，均可统一在该算法内。该方法用于钢筋混凝土结构ＣＡＤ软件的开发，从根本上提高了系统的可重用性、可维护性和可扩充性。同时，由于减少了一道矩形应力图形的简化步骤而提高了计算精度。
An object-oriented programming approach to conduct design of limit section strength of reinforced concrete members is presented in the paper. The approach, which involves numerical integration and solution to non-linear equations, encompasses the existing normal section strength theories of limit design principles which are charcterized by plane section assumption and failure of the outmost fibre when the ultimate compressive strain is reached.The algorithm has potential applications in the development of CAD softwares for the reinforced usability. maintainability and expansibility are achieved. The precision of results is also improved due to the reduction of one of the simplified procedures of rectangular stress contour.
