基于钢混协作关系的几何非线性分析法

Analysis Methods of Geometric Nonlinearity Based on Coordinating Relations of Steel and Concrete

介绍了基于钢混协作关系的非线性问题,分析了目前对钢筋混凝土结构的几何非线性分析方法,特别是TL列式和UL列式,同时介绍了几种几何非线性问题的求解方法。

Presenting briefly the nonlinearity based on the coordinating relations of steel and concrete,this paper mainly introduces the present analysis methods to solve the geometric nonlinearity,especially,total Lagangian formulation（T.L）and Updated Lagangian formulation（U.L）,and also provides ways to solve the geometric nonlinear equation.
