Abstract

This paper presents a nonlinear finite element analysis procedure for the seismic performance assessment of deep beam-and-interior column joints. A computer program, named RCAHEST(Reinforced Concrete Analysis in Higher Evaluation System Technology), for the analysis of reinforced concrete structures was used. Horizontal cyclic load tests were conducted to estimate the strength, ductility, and behavioral characteristics of deep beam-and-interior column joints. Experimental parameters are axial forces and amount of transverse reinforcement. The proposed numerical method for the seismic performance assessment of deep beam-and-interior column joints is verified by comparison of its results with reliable experimental results.

이 연구에서는 깊은보-내부기둥 접합부의 내진성능평가를 위한 비선형 유한요소해석 기법을 제시하였다. 사용된 프로그램은 철근콘크리트 구조물의 해석을 위한 RCAHEST이다. 깊은보-내부기둥 접합부의 강도, 연성도 등 거동특성을 파악하기 위한 반복횡하중 실험을 수행하였다. 실험의 변수로는 축력과 횡방향 철근량을 정하였다. 이 연구에서는 깊은보-내부기둥 접합부의 내진성능평가를 위해 제안한 해석기법을 신뢰성 있는 실험결과와 비교하여 그 타당성을 검증하였다.
