H-SA700Bを用いた柱梁溶接部の変形能力に及ぼす梁端ディテールの影響 [in Japanese] Effect of Beam-end Details on Deformation Capacity of Beam-Column Connections Made of H-SA700B High-Strength Steel [in Japanese]
Access this Article
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.
