STUDY ON DEFORMATION CAPACITY OF SITE WELDING BEAM-TO-COLUMNS JOINTS WITH THE METHOD OF DRILLED FLANGE

Part 2 Influence which different member section of beam give to deformation capacity

Abstract

This paper presents the result of full-scale test of site welding beam-to-column joints with the method of drilled flange and threedimentional elastic-plastic finite element analysis. Based on the test result, the method of drilled flanges have large deformation capacity as compared with common site welding beam-to-column joints. In stress ratio is over 1.05, deformation capacity of the specimen which was used the method of drilled flange improved over two times larger than that wasn't used the method of drilled flange. Based on the analysis result, in case that the hole position is too near to column face, the method of drilled flange can't decrease stress concentration of the scallop part. So we should plan hole position is 0.75 times as long as flange width.
