钢筋混凝土异形柱框架-短肢剪力墙结构参数分析
Parameter analysis of RC frame-short pier shear wall structure with special-shaped columns
【摘要】 针对异形柱框架-短肢剪力墙这种新型结构体系,采用动力和静力弹塑性分析方法,系统研究了罕遇地震下轴压比、短肢墙纵向配筋率及墙体截面高厚比等参数对整体结构抗震性能的影响.研究结果表明,该结构体系的抗震能力及延性随着底层墙、柱轴压比的减小,短肢墙配筋率的增大而显著提高;墙体截面高厚比不仅是结构体系的评判标准,也是影响结构延性的一个重要参数.通过参数分析,为异形柱框架-短肢剪力墙结构的合理设计提供了参考和依据.
【Abstract】 Studies the influence of such parameters,as axial-force ratio,reinforcement ratio and height-thickness ratio of wall on the seismic behavior of a new style structure system,reinforcement concrete frame-short pier wall structure with special-shaped columns,by means of the dynamic and the static elastic-plastic analysis method.The result shows that the aseismic ability and ductility performance of the structure are improved with the reduction of axial-force ratio and the augment of reinforcement ratio of walls.Height-thickness ratio of walls is not only the criterion of structure system,but also an important parameter for ductility of the strucure.Through analysis of parameters,this article proposes reference and basis for the design of the frame-short pier wall structure with special-shaped columns.
