이 논문에서는 적층단면법에 기초하여 단조하중 또는 반복하중을 받는 철근콘크리트 보 및 기둥 부재의 비선형 해석모델이 제안되었다. 완전부착 가정을 토대로 하고 있는 적층단면법은 콘크리트와 철근 사이의 부착슬립 거동을 고려하지 못한다는 고전적 비선형 해석법과는 달리, 균열 발생시 철근을 따라 발생되는 부착슬립 거동을 힘의 평형관계와 변위의 적합조건으로 정량화하고, 그 결과로부터 철근의 강성을 보정해줌으로써 반영하도록 하였다. 이는 적층단면법에서 추가 자유도(double node)를 도입하지 않고 부착슬립효과를 고려할 수 있다는데 그 의의를 둘 수 있을 것이다. 나아가 제안된 방법에 의한 해석결과와 실험결과와의 비교를 통해, 제안된 방법은 부착슬립 거동에 의한 강성저하(stiffness degradation)를 동반하는 철근콘크리트 보 및 기둥 부재의 균열거동을 효과적으로 고려할 수 있음을 검증하였다.

Abstract

An analytical procedure to analyze reinforced concrete(RC) beams and columns subject to monotonic and cyclic loadings is proposed on the basis of the layered section method. In contrast to the classical nonlinear approaches adopting the perfect bond assumption, the bondslip effect along the reinforcing bar is quantified with the force equilibrium and compatibility condition at the postcracking stage and its contribution is implemented into the reinforcing. The advantage of the proposed analytical procedure, therefore, will be on the consideration of the bond slip effect while using the classical layered section method without additional consideration such as taking the double nodes. Through correlation studies between experimental data and analytical results, it is verified that the proposed analytical procedure can effectively simulate the cracking behavior of RC beams and columns accompanying the stiffness degradation caused by the bond slip.
