摘要:
基于Panagiotou等提出的双塑性铰区设计概念，分别对6种不同塑性铰区数量和布置位置的模型进行非线性时程分析，对比罕遇地震作用下不同模型的受力情况。结果表明：塑性铰区数量超过3个时，结构的地震内力基本保持不变；当塑性铰区数量确定时，均匀布置使结构受高阶振型影响最小；沿高度方向均匀布置3个
Abstract:
The design concept of multi-plastic hinge region provides a new seismic idea of shear wall structure in high seismic areas. In order to achieve the balance of economy and security, it is necessary to determine the reasonable arrangement of multi-plastic hinge region. Based on the concept of dual-plastic hinge design put forward by Panagiotou et al.,the nonlinear time history analysis was carried out on 6 multi-plastic hinge region models of different quantity and arrangement respectively, comparing the seismic demand of different models. The results showed that when the number of plastic hinge region exceeds three, the seismic demands of the structure almost remain unchanged. When the number of plastic hinge region remained the same, the plastic hinge region located in different position had different influence of seismic internal force. When the plastic hinge region were uniform arranged, it is the most effective for reduction of the effect of higher modes. Arranging three plastic hinge region evenly along the height direction will significantly reduce the seismic demands of the structure under rare earthquakes, enhance the seismic performance of the structure, and produce good economic benefits
