SEISMIC REINFORCEMENT METHOD FOR EXISTING REINFORCED CONCRETE MOMENT FRAME BUILDINGS USING SECTIONAL ENLARGEMENT

摘要

The present invention relates to a seismic reinforcement method for existing reinforced concrete moment frame buildings to improve the strength, the stiffness, and the seismic performance of an existing reinforced concrete moment frame building by integrating a steel concrete composite reinforcing member with the structural member of the existing reinforced concrete moment frame building such as a school building having a long longitudinal side. According to an embodiment of the present invention, the seismic reinforcement method for existing reinforced concrete moment frame buildings comprises a step of chipping the exposure of reinforcing target column and beam (a); a step of installing a connector on the exposure of the column except for the joint (b); a step of installing an anchor bolt on the exposure of the beam and on the joint between the column and the beam at regular intervals (c); a step of attaching an H-beam to the exposure of the joint between the column and the beam and attaching a vibration damper to both ends of the H-beam on the exposure of the beam and to the H-beam on the outer side of the vibration damper in order (d); a step of pouring concrete to a filler placing space (e); a step of joining a first permanent form to the connector to cover the column and the beam except for the joint (f); a step of joining a second permanent form having the same cross-section as the first permanent form to the connector to cover the exposure of the joint between the column of the beam (g); and a step of placing a filler in the filler placing space between the first and second permanent forms (h).;COPYRIGHT KIPO 2014
