摘要
通过模型试验，对应县木塔层间恢复力特性进行了研究．根据原型沿竖向以明层和暗层交替迭合的结构特点，本次设计的层间模型包括一明层和一暗层，下明上暗，并按原型第二层以１０∶１缩尺制成．经过低周反复荷载试验，得到了３种竖向荷载下的水平恢复力滞回曲线及其特征．可用以对原型结构各层的恢复力及抗力等性能进行研究。
Properties of storey restoring force of Yingxian Muta are investigated by model tests. Similarly to the primary structure, the storey model includes an obvious storey and a hidden storey, which is made on the scale of onetenth according to the second floor. The hysteresis loops of restoring force are obtained under reversed cyclic loading and 3 kinds of constant vertical loading. These can be used to study the corresponding properties of the primary structure, which is the fundamental work in the analysis of the earthquake responses and seismic reliability of the whole wooden structure.
