STUDY ON DEFORMATION CAPACITY OF SHOP AND SITE WELDING BEAM- TO-COLUMN JOINTS WITH WELD DEFECT

Abstract

The weld defect of the welded beam-to-column joint in steel structure causes the brittle fracture and has possibilities to reduce the deformation capacity. It is considered that the effect of the weld defect on the deformation capacity from the difference of between shop and site welding beam-to-column joints is different. Therefore it is important to understand this difference.
In this paper, full-scale welding test was done it were shop and site welding beam-to-column joints. Then, the effect of the deformation capacity of test specimens caused by the difference of the position of welding defects between two joint methods was studied. As the results, the deterioration of deformation capacity caused by the welding defect was low using shop welding beam-to-column joints, and high using site welding beam-to-column joints.
