| 概要 |
The purpose of this study is to clarify the structural performance of concrete-filled box section column to beam connection panel made of ultra-high strength steel (H-SA700B) assembled by undermatched... welds. We conducted monotonic loading tests and experiments in which a constant axial force and repeated shear forces were applied to the beam-to-column connection of a cruciform subassemblage. Experimental parameters include strength of the weld metal at corner joint, width-to-thickness ratio, panel aspect ratio and others. Based on the results, it is revealed that a CFT panel assembled by undermatched welds has the sufficient performance for practical use. Furthermore, the shear strength equations, which can evaluate the effect of the weld metal strength at corner joints of panel, were proposed.続きを見る
