【摘要】 将大开间密肋复合墙结构与基础隔震技术相结合,可以有效地减小大开间密肋复合墙结构的地震响应。运用有限元分析软件SAP2000,对隔震大开间密肋复合墙结构模型进行动力分析,研究在地震作用下铅芯橡胶支座屈服比的变化对隔震大开间密肋复合墙结构隔震效果的影响。研究表明,对输入的各种地震波及其幅值,铅芯橡胶支座不仅可以取得明显的减震效果,而且可以找到一个最佳屈服比使大开间密肋复合墙结构的最大层间剪力最小,同时获得最大的控制效果。更多还原

【Abstract】 Make the large bay multi-ribbed composite wall structure system and the base isolation technology to unify,which can reduce effectively the seismic response of the large bay multi-ribbed composite wall structure system.The large bay multi-ribbed composite slab structure with lead laminated rubber bearings were established in the SAP2000 analysis software.Through the structure dynamic analysis,discuss the change of the yield ratio of seismically isolated bearing,which bring influence to the structure overall earthquake resistance.The analysis results show that lead laminated rubber bearings not only can achieve obvious damping effect,but also can find the best yield ratio to make the biggest interlaminar shear of the large bay multi-ribbed composite wall structure least.更多还原
