【摘要】 为了研究金属阻尼器在高层建筑中的耗能减震效果,在研究金属阻尼器耗能特性的基础上,利用非线性动力时程分析方法,对使用金属阻尼器的某高层建筑进行了8度大震作用下结构的弹塑性反应分析,对比了建筑物的自振周期和振型,绘制了3种地震波作用下的层间位移角曲线,并作了比较分析。结果表明,金属阻尼器耗能特性较好,高层建筑层间位移角明显减小,墙与连梁的破坏程度减小,达到了良好的耗能减震效果。该成果对金属阻尼器在高层建筑中的应用具有一定的参考意义。更多还原

【Abstract】 In order to research energy dissipation and earthquake mitigation effect of metal dampers in high-rise building,elastoplastic time history analysis of a high-rise isolated structure was implemented under imput of intensity 8 strong earthquake,and then the authors contrasted natural vibration period and vibration model,ploted interstorey drift angle curve of the structure under the action of three kinds of seismic wave,and carried out an comparative analysis.The calculation results show that energy dissipation characteristics of the metal damper is favorable,the damper decreases obviously interstorey drift angle and the destruction of wall and coupling beam of high-rise building,achieves a good energy dissipation and earthquake mitigation effect.The result obtained can provide a reference to application of metal damper to earthquake isolation of high-rise buildings.更多还原
