Abstract
The purpose of this study is to clarity the influence of beam-end details on the fracture and deformation capacity of beam-to-column connections made of H-SA700B high-strength steel. This paper presents the results of full-scale tests of site-welded beam-to-column connections with four types of the beam-end details: straight, cutout type horizontal haunch, weld type horizontal haunch and drilled flange. Based on the test results, both of the two types of horizontal haunch beam-to-column connections can avoid brittle fracture and have larger deformation capacity compare to the straight beam-to-column connection. However, the drilled flange beam-to-column connection cannot avoid brittle fracture.
