摘要：为减小发生地震情况下高层建筑的损坏，对高层建筑结构抗震性能设计方法进行研究，确定工程建筑结构的抗震性能目标和抗震性能水平，并进行多级抗震仿真测试实验对建筑的抗震性能进行评估。运用ABAQUS有限元软件建立有限元模型，通过对建筑内部结合结构的形变情况进行反应谱分析，得到建筑结构模型的X向和Y向平动质量系数。采用新型抗震探测器用于建筑结构抗震波动探测，模拟地震作用下实验结果显示，该系统设计的建筑结构模型抗震效果最好，在地震波作用下底层最大剪力低于
15 000 kN，层间位移最小低于5 mm。

Abstract：In order to reduce the damage of high-rise buildings in the event of earthquake，this study analyzes the seismic performance design method of high-rise building structures，determines the seismic performance target and seismic performance level of engineering building structures，and evaluates the seismic performance combined with the multi-level seismic idea. The finite element model is established by using ABAQUS finite element software，and the response spectrum analysis is carried out to analyze the internal force of the structure and the deformation of the structure，then the translational mass coefficients in X and Y directions of the building structure model are obtained. The new anti-seismic detector is used to detect the anti-seismic wave of building structures. The experimental results under simulated earthquake show that the seismic effect of the building structure model designed by the research system is the best. Under the action of seismic wave，the maximum shear force of the bottom floor is less than 15 000 kN and the minimum interlayer displacement is less than 5 mm.
