摘要
当前针对主体结构抗震性能的研究很多,但针对非结构构件抗震性能研究较少。为此,对高层建筑中非结构构件的抗震性能进行试验分析。利用统一建筑规范对非结构构件抗震计算进行规定,通过FEMA273、FEMA356依次对非结构构件性能与设计方法进行规定。选用楼面反应谱法对非结构构件抗震性能进行分析。将加速度看作调整核心,完成对加速度时程曲线振幅的调整,将其看作试验加速度波。地震波选用EL Centro-NS、Taft-NS与天津-NS地震波。通过ANSYS软件建立模型,获取不同楼层楼面反应谱,通过时程分析,采用ANSYS软件对吊顶抗震性能以及有无设置45°悬吊线吊顶抗震性能进行分析。通过非结构构件模拟器进行浮放设备抗震性能试验分析。依据试验得出以下结论:楼层越高,吊顶和浮放设备越容易在地震作用下被损坏;设置45°悬吊线能够有效提高抗震性能。
Although there are many researches on the seismic performance of a main structure,studies on the seismic behavior of non-structural components are scarce.Therefore,the seismic performance of non-structural components in high-rise buildings was tested and analyzed.The aseismic calculation of non-structural components was stipulated by the unified building code,and the performance and design methods of non-structural components were regulated by FEMA(Federal Emergency Management Agency,USA)273 and FEMA 356 in turn.The seismic response of non-structural components was analyzed by floor response spectrum method.The acceleration was regarded as the core of adjustment,and the amplitude of acceleration time curve was adjusted as the acceleration wave.Seismic waves were selected by EL Centro-NS,Taft-NS and Tianjin-NS seismic waves.Using the ANSYS software,the model was established to obtain the response spectrum of the floor.By the time history analysis,the seismic performance of the ceiling and the aseismic performance of the suspended ceiling with or without 45°suspension line were analyzed with the ANSYS software.The seismic performance test of floating equipment was carried out with a non-structural component simulator.According to the experiment,it is concluded that the higher the floor,the more easily the ceiling and the floating equipment are damaged under the earthquake action,and the 45°suspension line can effectively improve the seismic performance.
