摘要
将面向对象的程序设计方法用于桥梁结构分析程序的设计,系统阐述了体外预应力效应相关类的设计和实现方法。依据体外预应力效应的有限元分析方法,开发了体外预应力索的导线点类、体外预应力索的索单元类和体外预应力钢索类,完成了桥梁体外预应力效应计算过程的总体抽象和封装,实现了体外预应力效应的计算机仿真模拟。算例表明,设计的体外预应力相关类能够正确计算桥梁结构的体外预应力效应。
This paper introduces object-oriented programming method into the design of external prestress effect procedure. Based on the finite element analysis approach, the control point class, the tendon element class and the external tendon class are proposed, which implements an overall abstraction and package for the calculations of the effect of external prestress. It is proved by the example that the procedure designed in this paper can give reliable analysis and accurate results in the study of external prestress effect for bridge structures.
