Abstract

Fracture behaviors of composite beam-to-SHS column connections have scarcely been studied. In this study, a series of tests on beam-to-column connections were carried out with regard to mechanical properties of beam materials (low toughness hot-Rolled H-section vs high toughness hot-Rolled H-section) and geometrical condition of the welded joints.The obtained results are as followings:(1)The specimens with composite beam have smaller deformation capacity than the specimens with steel beam has. It was considered to be attributed to the strain concentration at the beam tension flange by the shift of the position of plastic neutral axis at the beam end.(2)General yield and maximum strength of beam end joint can be estimated by assuming yield line mechanism, respectively.
