T型钢连接框架边柱空间节点抗震试验研究
Experimental study on seismic performance of spatial beam to side column connection with T-stub
摘要
Abstract
The aim of this study is to evaluate the seismic performance of spatial semi-rigid beam-col-umn connections with T-stub.With the side column connection of steel frame as the research obj ect, spatial quasi-static tests were carried out,which load was applied to the column.There are two spatial T-stub connection specimens,two plane T-stub connection specimens and a spatial rigid connection specimen.According to the test phenomenon different deformation characteristics,plastic develop-ment characteristics and failure modes were investigated.Test data was collected for the analysis of the strength,rotational stiffness,hysteretic property,ductility coefficient and energy dissipation characteristics of the different specimens.The difference mechanical properties between the spatial T-stub connections and plane T-stub connections and also spatial rigid connection was verified.The re-search results indicate that under the action of spatial loads,the relevant mechanical properties of the spatial semi-rigid j oints were affected to varying degrees.关键词
