摘要
分析了西安鼓楼的防震构造,建立了鼓楼上部木结构的三维有限元模型,并对有限元模型输入Elcentro波(加速度峰值400gal)作为地震激励,进行了柱根和柱顶的位移及加速度曲线等分析.结果表明:防震构造有利于鼓楼的抗震,鼓楼柱础与木柱的连接形式具有一定的隔震效果,上部木结构具有减震耗能的能力,鼓楼具有良好的抗震性能.
The antiseismic constitution of Xi′an Drum Tower was analyzed in this paper.The finite element model of the upper timber structure in Drum Tower was established.The EL Centro wave（peak value of acceleration reachs 400gal） were chosen as input excitation on the finite element model,and the displacement curves and acceleration curves for the column root and column head was analyzed.The results show that the antiseismic constitution is benefit for the antiseismic performance of Drum Tower;the connection form for the column bases and columns has the effect of shock isolation;and the upper timber structure has the capacities of shock absorption and dissipation energy.Drum-Tower therefore has a good antiseismic performance.
