【摘要】 通过对双肢剪力墙的静力推覆分析(Push-over分析)揭示其极限状态的多种形式并提出连梁强度折减系数K,对在理想极限状态下的连梁剪力超强进行折减,得出对应于不同极限状态下连梁对墙肢轴力的改变量,可用于双肢剪力墙结构超强的整体计算,为带转换层的高层建筑转换结构的能力设计提供了理论基础。更多还原

【Abstract】 Through a push-over analysis,various limit states of coupled shear walls were disclosed,and the reduction factor K for the strength of coupling beams was put forward to reduce the shear overstrength of the coupling beams under an ideal limit state.The change of the axial forces of shear walls corresponding to different limit states can be obtained,and the overstrength of the whole coupled shear wall can be calculated,which offers a theory foundation to the capacity design of transfer structure in tall buildings with transfer stories.更多还原
