A method for reinforcing a steel frame structure, using an unit modular earthquake load absorbing device, according to the present invention comprises: (a) a step of demolishing a partition wall in a steel frame structure composed of steel frame columns and beams; (b) a step of arranging unit modular earthquake load absorbing devices in a row to form an impact-cushioning space unit by coming in contact with an impact damping unit, and of fixating each unit modular earthquake load absorbing device on upper and lower beams, wherein the unit modular earthquake load absorbing device is composed of: a corrugated web on which the impact damping unit, which has a form in which the center part of both ends of a corrugated steel sheet is inserted into a space composed of the steel frame columns and beams, and supporting members formed on the upper and lower ends of the corrugated web respectively by including an H-shaped steel beam and end plates formed on both ends thereof; and (c) a step of installing multiple finish panels on the front side of the space composed of the steel frame columns and beams, of fixating an angle on the center part of the finish panel, and of combining and installing the angle with and on the flange of the upper and lower beams. The method for reinforcing a steel frame structure is provided to simplify construction by being composed of a dry construction in which the earthquake load absorbing devices, which are unit-modularized, are arranged in a row and fixed, and which has the finish panel formed on the front side, and to efficiently improve the resistance ability of a building against earthquake load by displaying accordion effect according to plastic deformation which is generated by the corrugated web of the unit modular earthquake load absorbing device. |
