Plastic deformation capacity and fracture behavior of beam-end connection using built-up h-shaped beam: Structural characteristics of beam-end connection using pre-built-up h-shaped beam part 1

In this paper, structural characteristics of beam-end connection using various type built-up H-shaped beams are investigated by full-scale loading test. Main parameter is the geometrical and material properties at the bottom of weld access hole due to the fabrication method of built-up H-shaped beam. Test results, the brittle fracture of beam flange occurred in all specimens. The plastic deformation capacity of SBR specimen consisting of the pre-built-up H-shaped beam and the joint panel with a square hollow section is lowest; the capacity is 50% of the required performance. It was caused by lower two factors, the toughness of submerged arc weld metal and the joint efficiency of beam web connected part. © 2015, Architectural Institute of Japan. All rights reserved.
