PROBLEM TO BE SOLVED: To provide a steel-concrete composite member having excellent earthquake-resistant performance-wind pressure resistant performance instead of a conventional column-beam-earthquake resistant wall and a brace, to also provide a steelwork system shape steel plate earthquake resistant wall for improving shear-axial strength, and to further provide a perforated steel plate dowel of combinedly using a reinforced steel pipe and a dowel of high dislocation stop rigidity capable of transmitting axial force excellent in performance, in the present invention.SOLUTION: A steel-concrete composite column-beam cross section fills concrete in a steel tube by manufacturing the steel tube such as a squarish eight cross-sectional form by a plurality of steel plates. The steel plate of most contributing to the bending moment is relatively thickened, and is arranged on the outside. The width thickness ratio of its steel plate is proposed. A CFT system mega main reinforcement is installed in a giant column, and a triple steel pipe form concrete-filled steel pipe column having the composite confined effect is also proposed. While, on an earthquake resistant wall, the earthquake resistant wall of installing three sheets or more of steel plates in the in-plane direction in the wall, is provided.SELECTED DRAWING: Figure 4 |
