组合减震装置在连体结构高空连廊中的应用
|
摘要
为了保证高层连体结构连廊在地震作用下的使用安全以及减小连廊和主体结构之间的相互作用,在某复杂高层的连廊与主体结构连接处设置了铅芯橡胶支座和速度型粘滞阻尼器的组合减隔震装置.对连体结构进行在多种地震组合作用下的动力时程分析,计算结果表明该支座和阻尼器的组合装置对连廊和主体结构具有良好的减震消能作用,并且增设了本隔震装置后连体结构的各项指标均能满足抗震设计的要求.
To guarantee the safety of connective corridor in high-rise conjoined structure and reduce seismic interaction between connective corridor and major structures,combined isolation devices,and composed of lead rubber bearings and viscous dampers were adopted in a complex high-rise connected structure. In this paper,a time-history analytical method was employed to analyze the seismic behavior of the structure under earthquakes. The results show that the combined isolation devices have effects on seismic energy dissipation and responses reduction,and with the added combined isolation devices,the responses of structure can meet the requirement of seismic design.
