Experimental Study on Fracture Behavior of Built-up H-shaped Beams Connected with Rectangular Hollow Section Columns

Abstract

Full-scale fracture tests were carried out to investigate the influence of the types of scallops and toughness on fracture behavior of built-up H-shaped beams. Test results show that (1) although the different modes of fracture were observed between specimens which had scallops with boxing welding and without one, there was no remark able difference on the deformation capacity between them; (2) the difference of the defor mation capacity between specimens using high toughness hot-rolled plates and specimens using low toughness one appeared clearly.
