Research Status of Beam-Column Connection Joints of Assembled Steel Frame Structure in China
In the fabricated steel frame structure,beam-column connection joint is an important design content,and its structural rationality has an important impact on the safety and economy of the overall structure.In order to further study the related technologies of beam-column connection joints and promote the development of assembled steel structures,this paper summarizes and sorts out the research status of assembled steel frame beam-column connection joints in China in recent years.According to the different section forms of columns,it is divided into H-section steel column-steel beam connection joints and steel pipe column-steel beam connection joints.The construction and working characteristics of all types of connection joints are summarized and analyzed,and the existing problems and development direction of beam-column connection joints of assembled steel frame structure are discussed.
