摘　　要：结合震害资料,通过对算例的深入分析和比较,研究了高层建筑楼层侧向刚度突变的影响因素、控制方法及其对结构抗震性能的影响,对现行规范中层刚度比的控制方法提出了建议和补充。本文这一部分重点研究转换层的影响。By extensive computational analysis of several kinds of tall building structures and investigation of relative earthquake damage reports, the influencing factors, the control methods and the affects on seismic behaviors of the abruptness of lateral stiffness are studied in this paper. Some suggestions and supplements on the control methods of lateral stiffness ratio of adjacent storey used in the national codes are put forward. The key point of part Ⅱ is the influence of the transfer storey.

关 键 词：侧向刚度突变 楼层侧向刚度比 抗震性能
