SEISMIC REINFORCEMENT CONCRETE STRUCTURE USING STEEL BRACES WITH DAMPERS

摘要

The present invention relates to a seismic reinforcement concrete structure using a steel brace including a damper. The structure comprises: a beam installed in the upper part of an opening unit; and two parallel sides connected to the beam. Also, the structure is reinforced for an earthquake using the stele brace. The seismic reinforcement concrete using the steel brace comprises: a reinforcing frame comprising a horizontal frame installed at a lower end of the beam in the horizontal direction, and left and right vertical frames individually installed on the inner side of two parallel sides vertically connected to the beam by being extended in the longitudinal direction; first and second fixing steel plates individually attached to a predetermined position separated at the same interval to be symmetric from both ends of the horizontal frame to the inner side; third and fourth fixing steel plates individually attached to the predetermined position in the same height to be symmetric on one side end of the left and right vertical frames on the side; and the steel brace. A pair of braces have a symmetric structure. One end of the brace is individually connected to the first fixing steel plate and the second fixing steel plate, and the other end of the brace is individually connected to the third fixing steel plate and the fourth fixing steel plate. So, the brace is installed at a predetermined gradient angle. The first to fourth fixing steel plates are attached to a predetermined position of the reinforcing frame in which the brace does not interfere with the opening unit. The brace comprises a bracing steel pipe and a damper installed at both ends of the bracing steel pipe. So, a seismic reinforcing function is improved, and a phenomenon of blocking a view by blocking a window due to the brace is minimized. Moreover, the seismic reinforcement concrete structure maintains securement of the view and lighting and has fine appearance.
