초록
실무 및 연구에 있어서 반복하중을 받는 콘크리트 벽체의 변형 및 저항능력 그리고 재료의 변형율 등을 정확하게 평가할 수 있는 방법이 필요하다. 따라서 본 논문에서는 비선형 트러스 부재를 이용하여 반복 횡하중을 받는 철근콘크리트 벽체 또는 철근콘크리트 면부재를 모델링하였다. 콘크리트와 배근된 철근은 각각 수직, 수평 그리고 대각선 비선형 부재를 이용해 모델링되었다. 본 논문에서는 높이/폭 비가 1.2인 벽체를 예제로 선택하여 실험의 결과와 비교하였다. 비교를 위하여 주대각선 부재의 경로에 따른 4가지의 형상과 대각선 부재들의 배열에 따른 3가지 형상이 채택되어 실험 결과와 가장 근사한 모델링의 선택을 위해 평가를 실시하였다.
Abstract
Practicing engineers and researchers need computational tools that estimate accurately the cyclic response of RC walls, and in particular, force and deformation capacities and their materials strains. So this paper describes a nonlinear truss modeling approach for reinforced concrete walls, or in general, for plane stress reinforced concrete elements subjected to cyclic reversals. Nonlinear vertical, horizontal, and diagonal truss elements are used to represent concrete and steel reinforcement. The wall having aspect ratio of 1.2 was chosen to be compared with the experimental results. Here, four types of main diagonal member models and three types of diagonal members models were applied to find out more accurate results of analysis.
