摘要:
为了研究半刚性节点钢框架-加劲钢板剪力墙结构体系的抗震性能和传力机理,模拟实际框剪结构的底部两层,对一榀单跨两层1/3缩尺半刚性节点钢框架-十字加劲钢板剪力墙结构进行了抗震拟静力试验研究,在试验模型的基础上,建立了非线性有限元模型,并验证了模型的有效性.考虑影响结构抗震性能的4个主要因素:节点刚度、剪力墙厚度、框架柱的刚度、肋板刚度比,进行了4个系列16个有限元模型的变参数分析.结果表明:降低节点刚度有利于提高结构的延性和耗能能力;增加柱的刚度和肋板厚度可提高结构的初始刚度、承载力和延性性能;增加内填墙板的厚度,将降低试件的延性性能;内填墙板在加载初期非常有效,承担70%~85%的水平剪力,研究为该种结构体系的工程应用和理论分析提供依据
Abstract:
In order to study the seismic behavior and force distribution in the structural system of the semi-rigid composite steel frame with steel plate shear walls, based on the experiment of a one-third scale, one-bay, two-story semi-rigid composite steel frame model with cross-stiffened steel plate shear wall under lateral cyclic loads, a non-linear finite element analysis model was built, and then the finite-element analysis model was validated by experimental data. Parametric analyses of 4series and 16finite element models were performed, in which 4main influential factors including rotational stiffness of connections, different infill wall slenderness ratios, column flexibility, rigidity of stiffener were considered. The results showed that the reduction rotational stiffness of the connections may enhance the width of infill walls. Use of suitable parametric of column flexibility, rigidity of stiffener would improve the performance of the whole structure. The infill plates are the structure with the infill plates are very effective in the initial stages of loading. The infill plates undertakes70%~85%of overall lateral load. The research provides a basis for engineering application and theoretical analysis of the structural system
