摘要
通过对一栋剪重比偏高的超高层剪力墙结构的计算比较,分析了其二阶振型剪力偏大的产生原因、影响因素,结合二阶振型的变形较大楼层与避难层开洞楼层基本重合的特点,进一步探讨了此类受二阶振型影响的超高层结构在动力弹塑性分析时天然波的选择方式,比较了不同的选波方式在判断薄弱部位上的差异,并给出类似结构的选波建议。
Through the calculation and comparison of a super high-rise shear wall structure with high shear weight ratio, the causes and influencing factors of large shear force of its second-order vibration mode are analyzed. Combined with the characteristics that the floors with large deformation of the second-order vibration mode basically coincide with the floors with openings in the refuge floor, the selection mode of natural wave in dynamic elastic-plastic analysis of this kind of super high-rise structure affected by second-order vibration mode is further discussed. The differences of different wave selection methods in judging the weak parts are compared, and the wave selection suggestions of similar structures are given.
