Linear and Nonlinear Strut-Tie Model Approaches for Analysis and Design of Structural Concrete

콘크리트 부재의 해석/설계를 위한 선형 및 비선형 스트럿-타이 모델 방법

In this paper, the linear and nonlinear strut-tie model approaches for the analysis and design of concrete structures are suggested. The validity of the approaches are examined through the strength analysis of four dapped-end beams tested to failure. According to the analysis results, the nonlinear strut-tie model approach which takes the various characteristics of nonlinear behaviors into account in the analysis and design of structural concrete and predicts the strength of structural concrete proven to be an effective method for structural analysis and design.
