Abstract
In residential construction,concrete-filled steel tube(CFST)structures are a commonly used building form.Among the connections between steel beams and CFST columns,the three main types are internal diaphragm connections,external diaphragm connections,and through-diaphragm connections.The connection method is a primary factor influencing the mechanical behavior of the components and represents a relatively vulnerable area in seismic design.Therefore,research on beam-column connections is a key and challenging issue in structural studies.Based on recent research progress and findings,this paper summarizes the mechanical performance and design methods of these three types of connections.It also highlights the main existing problems in CFST column-to-steel beam connections and provides an outlook on their future trends.关键词
