BRACE DAMPER AND SEISMIC CONTROL STRUCTURE OF BUILDING CONSTRUCTION USING IT

摘要

PROBLEM TO BE SOLVED: To provide a brace damper which is simple in constitution and low in manufacturing cost by providing a joining part to be rigidly connected to a column or a beam on each end of a seamless tube of circular section made of extremely soft steel. ;SOLUTION: Brace dampers 20A, 20B in which joining parts 22... are provided on each end of seamless tubes 21, 21 of circular section made of extremely soft steel are prepared. A pair of brace dampers 20A, 20B are arranged in a rectangular space 10 to be surrounded by a column 1, an upper beam 2, and a lower beam 3 to constitute a building. A pair of brace dampers 20A, 20B are diagonally arranged in a line symmetric to the perpendicular axis to split the space 10 in the right-to-left direction. A joining part 22 of each end of the brace dampers 20A, 20B is rigidly connected to gusset plates 31, 32, 32 provided on the column 1, and the beams 2, 3 through connection plates 31a..., 32a....;COPYRIGHT: (C)1997,JPO
