It is founded that the stress concentration at joints of CFST is a quite different from that of hollow steel tube. A conclusion can be made that analysis of fatigue at the joints of CFST truss arch bridge can not apply the results developed from analyzing at joints of hollow steel tube in marine structure.展开更多
文摘In this paper stresses at joints forming by hollow steel tube and concrete filled steel tube (CFST) are calculated, analyzed and compared. It is founded that the stress concentration at joints of CFST is a quite different from that of hollow steel tube. A conclusion can be made that analysis of fatigue at the joints of CFST truss arch bridge can not apply the results developed from analyzing at joints of hollow steel tube in marine structure.
