A STUDY ON COLLAPSE MODE AND PLASTIC DEFORMATION CAPACITY OF HIGH STRENGTH STEEL BEAM CONNECTED TO BOX COLUMN

摘要

In this study, he collapse mode and the plastic deformation capacity of 590N/mm~2 high strength steel beam with scallops connected to box column is investigated by the monotonic loading test and the numerical analysis. And the stress transfer quantity for beam web to column is investigated too. It is clear that this quantity is influnced by column plate thickness greatly and not depend on the web thickness. As aresult, if this quantity is small, beam collapses with fracture. Particular, beaation capacity becomes small.
