摘　　要：为提升高层建筑在地震作用下的抗震性能,特别是针对框架-铰支摇摆剪力墙结构,研究建立了连续化的力平衡方程和微分方程,对结构模型进行简化.基于地震能量平衡原理,进行塑性设计,精准计算出关键部位的弯矩和内力分布情况.同时,通过弹塑性时程分析,对结构的抗震性能进行了校核.结果表明:阻尼器的使用在8层结构中将最大位移角从1.0%以上降低到0.9%以下,在12层结构中从1.2%以上降至1.0%以下.这些数据证明,阻尼器的加入显著提升了结构的抗震性能.In order to improve the seismic performance of high-rise buildings under earthquake action,especially for frame hinged sway shear wall structures,a continuous force balance equation and differential equation were established to simplify the structural model.Based on the principle of seismic energy balance,plastic design was carried out,and the bending moment and internal force distribution of key parts were calculated.Meanwhile,the seismic performance of the structure was verified through elastic plastic time history analysis.The results indicate that the use of dampers reduces the maximum displacement angle from above 1.0% to below 0.9% in an eight-story structure,and from over 1.2% to within 1.0% in a twelve-story structure.These data demonstrate that the addition of dampers significantly improves the seismic performance of the structure.
