防灾减灾学报

抗震支吊架与建筑结构体相连接，在地震发生时能够有效保护建筑机电设施，降低地震引起的次生灾害风险，因此，研究抗震支吊架的抗震性能具有十分重要的意义。在抗震支吊架抗震性能的试验方法中，模拟地震振动台试验相较于拟静力试验和拟动力试验，是检测机电系统抗震性能最为科学的方法。该方法通过模拟承受三向六自由度的荷载、考虑加速度效应以及高频率的振动，能够再现结构试件在地震作用下的受力过程，进而验证其是否具备抗震性能。本文结合现行规范标准，并根据抗震支吊架的特性和实际应用工况，研究制定了抗震支吊架模拟地震振动台试验方法，并给出了一些相关建议。

The seismic support and hanger are connected with the building structure,which can effectively protect the building mechanical and electrical facilities in the earthquake, reduce the secondary disasters caused by the earthquake,so it is of great significance to study the seismic performance of the seismic support and hanger. In the seismic performance test method of seismic support and hanger, the simulated seismic shaking table test is the most scientific method to detect the seismic performance of the electromechanical system compared with the quasi-static test and the quasi-dynamic test,and whether it has seismic performance is verified by simulating the load, acceleration effect and high-frequency vibration of the three-way and six-degree-of-freedom load,acceleration effect and high-frequency vibration,and reproducing the stress process of the structure or specimen under the seismic action. In this paper, combined with the current norms and standards, according to the characteristics and application conditions of seismic support and hanger,the seismic support and hanger simulation seismic shaking table test method is studied and formulated,and some suggestions are given.
