摘要
本文研究了安装粘弹性耗能器结构在常遇地震作用下层间最大剪力的分配情况 ,给出了层间最大剪力在结构构件与耗能器之间按刚度分配原则进行假想分配后 ,所得假想层间构件力与层间最大构件力之间的关系 ,以及假想层间附加力与层间最大附加力之间的关系 ,探讨了罕遇地震作用下安装粘弹性耗能器结构与安装软钢耗能器结构的层间弹塑性变形简化计算方法。
The distribution problem of the maximum interstory shear force under mild earthquakes among structural members and viscoelastic dampers is studied. The relationship between the maximum interstory member force and the virtual interstory member force, and the relationship between the maximum interstory additional force and the virtual interstory additional force are proposed respectively for structures with viscoelastic dampers. A simple method for calculating the elastoplastic interstory drifts of structures with viscoelastic dampers and ADAS dampers under strong earthquakes is suggested.
