Abstract

This study evaluates the seismic performance of reinforced concrete (RC) flat plate structures relation to the gravity shear ratio. For this purpose, 3 and 7 story framed buildings were designed for gravity loads only. Subsequently, a nonlinear static pushover analysis and a nonlinear time history analysis for the prototype buildings were carried out. In the nonlinear analysis, newly propose analytical slab-column joint model was utilized to capture punching shear failure and fracture mechanism in the analysis. The analytical results showed that seismic performance of RC flat plate frame is strongly influenced by the gravity shear ratio. In particularly, in the RC flat plate frame with a large gravity shear ratio the lateral strength and maximum drift capacity decreased significantly.

이 연구에서는 중력 전단비에 따른 철근콘크리트 플랫 플레이트 골조의 내진성능을 평가하였다. 이를 위하여, 이 연구에서는 3층, 7층 골조를 중력하중만 고려하여 설계하고, 대상 건물에 대한 비선형 정적 푸쉬 오버 해석과 비선형 동적 해석을 수행하였다. 그리고 이 연구는 그 비선형 해석에서 중력 전단비의 차이에 따른 뚫림 전단과 파괴 메커니즘을 예측할 수 있도록 제안한 슬래브-기둥 접합부 모델을 사용하였다. 이 연구 결과에 따르면 중력 전단비가 골조의 내진성능에 큰 영향을 미치는 것으로 나타났다. 특히 중력 전단비가 커짐에 따라 골조 접합부의 파괴가 취성적인 파괴를 나타내어 내진 성능이 떨어지는 것으로 나타났다.
