带可更换耗能摩擦板的自复位钢柱脚节点抗震性能试验研究
Experimental study on seismic performance of self-centering steel column-base connections with replaceable energy-dissipating friction plates
摘要
Abstract
To achieve rapid post-earthquake functional recovery of steel frame structures,a column base joint with replaceable energy-dissipating friction plates was proposed.In this joint,high-strength anchor bolts combined with disc springs provided the restoring force,thereby effectively improving the self-centering performance of the joint.Meanwhile,energy was dissipated through the plastic deformation of the energy-dissipating friction plates and the friction between the friction plates and shim plates,ensuring that plastic deformation was concentrated in the replaceable energy-dissipating friction plates and preventing irreversible plastic damage to the main body of the column base.To investigate the seismic performance of this type of connection,quasi-static tests were performed on a total of five specimens,including a conventional steel column base and recoverable column bases with energy-dissipating components.The energy-dissipating components included buckling energy-dissipating plates and energy-dissipating friction plates.The results demonstrate that the recoverable steel column base joints display substantially improved bearing capacity and energy dissipation capacity,while also enabling rapid replacement.Damage is concentrated primarily in the energy-dissipating components and cantilever plates,and the steel column remains elastic even when the inter-story drift ratio reaches 5％.After replacement of the damaged energy-dissipating components,the column base can restore its original hysteretic performance,with increased rotational stiffness but slightly reduced self-centering capacity.The total cumulative energy dissipation of the column-base connection with energy-dissipating friction plates was 51.5％and 112.48％higher than that of the connections with buckling energy-dissipating plates and without energy-dissipating components,respectively.关键词
