对称型摩擦连接幕墙节点抗震性能研究
Study on seismic performance of curtain wall joint with symmetric friction connection
摘要
Abstract
To achieve deformation coordination between a frame-supported glass curtain wall and the two connected towers,a joint with a symmetric friction connection(SFC)was proposed.The configuration of the joint was described,and its deformation capacity and seismic performance were investigated through cyclic loading tests and numerical analysis.Tests under five loading cases examined the effects of die spring usage,axial force application,and plate wear on the seismic performance of the joint.This study indicated that pre-compressed die springs provided a stable and uniform frictional sliding behavior,making their adoption recommended in the design.Plate wear was found to increase sliding resistance but reduce sliding stability.A finite element(FE)model was developed using ABAQUS to quantitatively evaluate the sliding behavior and energy dissipation characteristics.Within a±225.00 mm displacement range,the main components remained elastic,demonstrating the low-damage characteristics of the joint.The SFC achieves the design objectives of wind-load stability,post-frequent-earthquake sliding activation,and rare-earthquake deformation coordination with the connected towers.关键词
