高层建筑结构侧向刚度变化及其控制方法研究(Ⅰ)

Study on Changes and Control Methods of the Lateral Stiffness in Tall Building Structures(Ⅰ)

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。本文第一部分重点研究层高变化的影响。

By extensive computational analysis of several kinds of tall building structures and investigation of relative ea-~quake 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 Ⅰ is the influence by the changes of story height.
