摘要
本文详细讨论了钢框架节点区的受力和变形特性,建立了考虑节点区剪切变形的梁、柱单元分析方法。应用本文的单元分析方法,能够十分便利地直接由梁、柱和节点区的单元刚度装配得到考虑节点区剪切变形框架的总体刚度,因而结构的弹塑性地震反应分析和编制计算程序都十分简便。作者所进行的钢框架模型模拟地震振动台试验表明,节点区的剪切变形很大,有必要考虑其对结构地震反应的影响。试验分析证明,本文的理论是可靠的。
The behavior of steel frame panels are discussed in detail and an element method for analysis of beams and columns taking panel shear deformation into account is established in this paper. With applying the element method presented in this paper, the stiffness matrix of the whole frame possessing panel shear deformation can simply be obtained by the direct assemblage of element stiffness matrices of each beam, column and panel. Consequently, the analysis of structural elasto-plastic seismic response and the compilation of computer program become easier. The seismic shaking table tests of steel frame models conducted by the authors indicate that the panel shear deformation may be great and its effect on the structural earthquake response should be considered. The analysis of the tests demonstrates the theory of this paper is reliable.
