철골프레임으로 보강된 보통모멘트골조의 내진성능평가

Abstract

The purpose of this study is to evaluate the seismic performance of two-layer reinforced concrete frame reinforced by open frame method. Recently, interest in seismic reinforcement of school buildings is increasing, and various seismic reinforcement methods are proposed. The open frame method is a method of reinforcing the strength and rigidity of the seismic reinforcement method, a method of increasing the seismic performance through the enhancement of the cross section of the column and beam and the integration behavior of the steel frame and reinforced concrete frame. This study evaluated the suitability of seismic performance and seismic reinforcement of open frame method.
