STEEL FRAME STRUCTURE WITH COLUMN LEG RIGIDITY AND X-Y AXES RIGID JOINT FRAME WITH JOINT PART OF COLUMN AND BEAM JOINED BY HIGH-TENSION BOLT AND FILLET WELDING

摘要

PROBLEM TO BE SOLVED: To provide an earthquake-resistant and wind-resistant strong structure without any deviation in quality by using a bracket system constructed of a T-steel flange and a fillet-welded web plate and jointing to a column via high- tension bolt and fillet welding. ;SOLUTION: A rigid joint structure is constructed by using H-steel column 1 and H-steel beam 2 as a column and a beam for principal components. In combination with a flange T-steel 4 or a flange plate 5, a web plate 6 is fillet- welded for forming a bracket 3. In assembly, the flange T-steel is connected to the H-steel as a column or a base beam by means of a high strength bolt, while the flange plate and the web plate are connected together by fillet welding. A rigid joint part, which is the most import part in a skeleton building, is connected through tension joint by means of high-tension bolt, and a bracket system requiring no high precision in building is used. In this way, full penetration welding depending of a skill of a welder is dispensable, and stable strength hardly fluctuating in the strength based on a structural calculation result considering resistance against an earthquake and wind can be expected.;COPYRIGHT: (C)2001,JPO
