摘要
本文提出了一个用于杆系结构非线性分析的积分本构函数。由此导出了桁架和框架材料非线性分析的刚度方程式。表明本文提出的本构函数具有数值分析方便,能解决加载、卸载中较难的非线性分析问题。
In this paper, a constitutive function in form of integration is presented for a nonlinear analysis of structures of linear elements. With applications of a constitutive function, the truss and frame elements material nonlinear stiffness equations are derived. The results shows the convenience in numerical analysis and the ability to solve some difficult problems in tn the structural behavior study both in loading and unloading process by use of the presented constitutive function.
