Study on Designs to Prevent Fracture in Beam-to-Welded Box Column Connection Part2 Plastic Analysis of the Beam-End Connection

Abstract

To establish a design to prevent brittle fracture in H-beam-to-welded box column connection, the stress in vicinity of joints was investigated by finite analysis in Part 1. Its results show that the plastic deformation introduced into interior diaphragm is widely expanded. Then, to estimate the local plastic strength of the beam-to-welded box column connection considering the plastic deformation of interior diaphragm by the yield line theory is proposed.
