摘要
本文基于Clough双分量模型的思想,提出了钢杆件弹塑性单元刚度分析的瞬态广义Clough模型概念,结合考虑几何非线性,建立了杆系钢结构弹塑性变形实用分析方法。通过钢刚架模型试验的分析,验证了本文分析方法的有效性,同时指出了几何非线性对杆系钢结构弹塑性变形分析结果的影响。
Borrowing the thoughts of bilinear Clough model,a generalized transient Clough model for theanalysis of elemental elasto-plastic stiffness of steel members is proposed in this paper. Based on ourproposed model, a practical method for the analysis of elasto-plastic deformation of steel member struc-tures under wind, earthquake and various other loads is established with considering geometricalnonlinearity. Through the analysis of several steel frame models experimented in our university, the va-lidity of the method presented in this paper is checked and the effect of geometrical nonlinearity onelasto-plastic deformation of steel member structures is pointed out as well.
