Junction manner of the steel-frame cylinder of junction manner and the junction structure of the steel-frame cylinder and steel-frame beam

摘要

PROBLEM TO BE SOLVED: To provide a technique to join a steel-frame column and a steel-frame beam, which can relive stress concentration at a place where a steel-frame beam and a combining plate are fixed together when large external forces like an earthquake, etc. apply, is also effective in expanding the scope of application of the method to a steel-frame column with a large D/t (diameter/thickness ratio), and can also reduce the total length of beam bracket for joining use.;SOLUTION: As a component to connect a steel-frame column 1 and a steel-frame beam 2, connection plates 9, 10 are nearly vertically provided, for instance, in the vicinity of the joining end of a steel-frame beam 2 or the flanges 6, 7 of joining beam brackets 3, and at least part of an external side part between one fixing end of these connecting plates 9, 10 and the steel-frame column 1 and the other end is shaped to be concave. This forms a plasticization area that plasticizes before the points at the middle of connecting plates 9, 10 fixed to the steel-frame column 1.;COPYRIGHT: (C)2006,JPO&NCIPI
