摘要
高层建筑采用BRB和VFD并列混合被动控制模式,能充分发挥两种阻尼器的优点,更好的达到预期的减震效果。本文以某一高层医疗建筑为例,对传统抗震结构、BRB减震结构、VFD减震结构、BRB和VFD混合减震结构等5个模型进行了小震、大震下的时程分析。结果表明,在结构层间位移角相近的前提下,BRB和VFD混合减震结构的构件截面尺寸、结构地震剪力、含钢量等均小于其他结构,BRB和VFD混合减震结构大震下的抗震性能也优于其他结构,能更好地实现预期减震目标。
The high-rise building adopts the hybrid passive control mode of BRB and VFD, which can give full play to the advantages of the two dampers and better achieve the expected damping effect. In this paper, taking a high-rise medical building as an example, the time-history anaysis of five models including traditional seismic structure, BRB damping structure, VFD damping structure, BRB and VFD hybriddamping structure under frequent earthquake and rare Earthquakeis carried out. The results show that under the premise of similar inter-story displacement angle, the structural section size, seismic shear force and steel content of BRB and VFD hybrid damping structures are smaller than those of other structures. The seismic performance of BRB and VFD hybrid damping structures under rare earthquakes is also better than that of other structures, which can better achieve the expected damping objectives.
