Abstract:
Comparison experimental research on the ultimate strength of gusset plate joints of hollow steel tubes(HST)and concrete-filled steel tubes(CFST)were carried out in 12 specimens. The joints of steel tube with and without concrete infilling were compared. The static test results indicate that the load on gusset plate can be transferred to concrete composite column members, as long as the strength of welding that connects gusset plate and steel tube is enough. The bearing capacity and local buckling performances of CFST joints with gusset plate are much better than those of HST. This type of CFST joint can be used in composite truss systems and be more convenient than traditional connections.
