    • PROBLEM TO BE SOLVED: To provide an aseismic structure capable of being installed in a narrow space while having an attenuation section to add attenuation as well as a brace section which plasticizes when receiving a load.SOLUTION: An aseismic structure 10 comprises: an attenuation section 70 (an oil damper 71) which is installed inside a plane of structure 5 of a frame composed of columns 2 and beams 3 and adds attenuation to the frame; and a brace section 80 which has a first brace 81 and a second brace 82. In the brace section 80, when tensile axial force is generated in one of the first brace 81 or the second brace 82, a compressive axial force is generated in the other of the first brace 81 or the second brace 82. Also, when the tensile axial force exceeds a yield load, either of the braces 81 or 82 plasticizes. Moreover, the attenuation section 70 and the brace section 80 are arranged in parallel.

    • PROBLEM TO BE SOLVED: To provide a method for constructing a bridge capable of suppressing construction cost and maintaining the accuracy of the shape of the bridge while minimizing the occupied space under the bridge. SOLUTION: A bent 12 serving as a temporary pier is installed at a position apart from a first pier 2a in the direction of constructing the bridge 1. A bridge block 4 is installed between the bent 12 and the first pier 2a. A new bent 12 is installed at a position apart from the bent 12 positioned at the outermost end in the installation direction in the direction of installing it. The attitude of each existing bridge block 4 is measured, the completed shape of the bridge 1 is predicted according to the measurement information, and the connection angle ε between the bridge block 4 positioned at the outermost end in the installation direction and the newly installed bridge block 4 is so determined that the error of shape between the predicted completed shape and a target completed shape comes within the allowable range.

    • PROBLEM TO BE SOLVED: To provide an aseismatic repair method of an existing bridge allowing a hysteresis damper manufactured beforehand as designed, to be mounted as it is in a position where an existing brace was mounted. SOLUTION: The aseismatic repair method of the existing bridge comprises column members 14 supporting a bridge girder 12; a plurality of horizontal members 15 horizontally connecting these column members 14; and a plurality of braces 16 obliquely arranged between the column members 14 and the horizontal members 15. In this case, length adjustable temporary braces 17 are arranged almost parallel with the braces 16, and after the length of the temporary braces 17 are respectively adjusted to nullify dead load stress of the braces 16, the braces 16 are removed. Instead, hysteresis braces having equivalent plastic deformation characteristics to compressive force and tensile force are mounted, and then the temporary braces 17 are removed.
