Abstract

The strength efficiency of the welded beam web joint between rectangular hollow section column and wide flange section beam is influenced by the out-of-plane behavior of the column flange connected. The experimental and analytical research works were carried out to investigate the design formula of the flexural strength of the welded beam web joint. The flexural strengths estimated from the equality hypothesis of plastic virtual work proposed by authors and the upper bound theorem proposed by Suita and Tanaka, both assuming the same yield line mechanism are discussed in this study. From the results of finite element analysis on the elastic-plastic flexural behaviors of the model joints, the flexural strength proposed by authors agrees well with the general yield strength of the joint, which can also be applicable to estimate the plastic strength in the wide range of plastic deformation of the beam-to-column connection.
