COLUMN-BEAM CONNECTION STRUCTURE |
摘要 |
Bending moment applied to a beam causes out-of-plane deformation to a panel when the panel zone is hollow, and thereby a load bearing by a web cannot be expected in an elastic region. Since the section modulus of a beam end which is used in the structure calculation of a building structure is limited to the section modulus of only the flange not including the web, the beam end has a low strength. Therefore, a beam larger in size must be used and an extra beam depth is required, thus causing an increase in the weight of a steel beam. As the result of various studies, it has been found that various problems could be resolved by significantly increasing the plate thickness of a diaphragm in the direction of the web, and imparting prestress by hot working or overlaying the underside surface of the beam.
