Seismic Evaluation of Ordinary Moment Concrete Frames Using Capacity Spectrum Method

지반특성과 지진지역에 따른 보통모멘트 골조의 내진성능 평가

This study is to evaluate seismic performance of ordinary moment concrete frames. Base shear and roof displacement relations are obtained from the experiment of 3 story ordinary moment resisting concrete frame. The frame was designed only for gravity loads. The performance of the building is evaluated using capacity spectrum method. Five different seismic zones and three different soil types are considered. For each condition of seismic zone and soil type, ten earthquake ground motions are used to establish the demand spectrum.
