【Abstract】 Based on the experimentation of nine concrete\|filled square steel tubular (CSST) compression\|loaded X\|connections,the failure model and process of CSST compression\|loaded X\|connections are investigated,and main factors that affect bearing capacity and initial stiffness of CFST compression\|loaded X\|connection are analyzed.The results of experimentation show that the bearing capacity of CSST compression\|loaded X\|connection can be increased as ratio of web to chord width ( b ) or lengths of concrete ( L c) are risen,and the initial stiffness of such connections is enhanced as ratio of web to chord width is risen. \[更多还原
