PROBLEM TO BE SOLVED: To provide an earthquake resistant structure for a building, which ensures desired earthquake resistant strength, and has a simplified structure by dispensing with a buckling preventive member. SOLUTION: According to the earthquake resistant structure, a pair of right and left vertical members 14, 13 are connected to an upper girder 11 and a lower girder 12, and a plurality of diagonals 17 are arranged between the vertical members 14, 13, as earthquake resistant elements, in a manner extending diagonally with respect to the vertical members 14, 13. Each diagonal 17 has a linear shape as a whole, and connection edges 17a on both ends are secured to the vertical members 14, 13, by welding or the like, and a portion of the diagonal 17, inner than the connection edge 17a is formed into a plastic hinge portion 17b, which means that each diagonal 17 has two plastic hinge portions 17b. Then intersection points of the two diagonals 17 intersecting each other like the X, are rigidly connected together by welding. COPYRIGHT: (C)2008,JPO&INPIT |
