阻尼填充墙优化布置对不规则框架结构抗震性能的影响
Optimized Layout of Damping Infill Walls and Its Effect on theSeismic Behavior of Irregular Frame Structures
摘要
Abstract
The performance of infilled walls is very important in the local and global seismic performance of irregular frame structures.Continuous research on damping infill walls has greatly improved the seismic performance of infilled frames.However, complex construction technologies and high construction costs have rendered the large-scale use of this type of structure impractical.To reduce the difficulty and cost of construction and improve the seismic performance of the resulting frame structure, the anti-seismic performance of a damped infill wall in an irregular frame is studied.Considering the characteristics of an irregular frame structure, the damping infill wall is arranged in a variety of ways, and these layouts are compared via analyses of mode type, energy dissipation, and component utilization.Damping infill walls with better damping effects can be obtained when it is arranged in the position of each mode type.The utilization ratio of the structure changes when the damping infill wall is arranged around the member, and the energy consumption of the damping infill wall increases.This paper also proposes an optimal layout strategy of damping infill walls in irregular frame structures.Optimization of the local arrangement of damping infill walls is used to improve the seismic performance and reduce the construction difficulty and cost requirements of the final structures.This work provides some suggestions for the design of infilled frame structures.关键词
