摘要
建筑抗震支吊架在地震中能对建筑机电工程设施给予可靠的保护,因此,必须准确计算建筑抗震支吊架的地震反应并进行抗震设计。论文采用时程分析法建立了高层建筑抗震支吊架的抗震设计方法,详细阐述了高层建筑结构-支吊架的耦合计算模型、地震波的选取原则和地震作用的计算方法。框架结构、框剪结构和框筒结构的3个工程实例表明,采用时程分析法可以准确计算高层建筑抗震支吊架的地震作用,其相比等效侧力法具有显著的应用优势。
Anti-seismic hangers of buildings can provide reliable protection for building electromechanical facilities in earthquake. Therefore, it is necessary to calculate the seismic response of anti-seismic hangers and carry out seismic design. In this paper, the seismic design method of anti-seismic hangers of high-rise building is established by time-history analysis method. The coupling calculation model of high-rise building structure and anti-seismic hangers, the selection principle of seismic wave and the calculation method of earthquake action are de.scribed in detail. Three engineering examples of frame structure, frame-shear wall strucaLr~ and frame-core tube structure show that the time-history analysis method can accurately calculate the seismic action of anti-seismic hangers of high-rise buildings, and has significant application advantages compared with equivalent lateral force method.
