摘要
为了研究开明寺唐塔地震作用下的动态效应,通过力学性能试验确定塔的材料参数,建立塔体的数值模型,计算了结构动力特性,并根据场地条件选取El-Centro波作为地震动,分别按照7度小震、中震和大震进行输入,计算了塔体的动力响应,分析了加速度放大系数、层间位移、层间位移角随楼层高度的变化关系,研究结果可为古塔抗震能力评定提供参考。
In order to study the dynamic performance of Tang Pagoda in Kaiming Temple under the action of earthquake,mechanical property test was conducted to obtain material parameters of the pagoda.A numerical model was established to calculate the dynamic characteristics of th pagoda.El-Centro wave was adopted as earthquake ground motion according to the site condition.The dynamic response of pagoda body was calculated with the input of minor,moderate and major earthquake in seven levels,respectively.The acceleration amplification factor,the inter-storey displacement and the relationship between the inter-storey displacement angle and the storey height were all analyzed,the results can be referenced by seismic assessment to masonry pagodas.
