Abstract

The recent worldwide trend in construction industry tends to put emphasis on the performance based design which focuses on the suggestion of the performance of final products rather than method and procedures. A proper model should be employed when predicting the concrete strength, which reflects the material age, in order to verify the function of concrete structures and their materials. Accordingly, this paper proposes the concrete strength development constant (${\alpha}_{sc}$) reflecting the characteristics of domestic materials and then evaluates its suitability.

최근 건설시장의 세계적인 흐름은 방법 및 수행 절차보다는 최종 성과물의 성능을 제시하는데 초점을 맞춘 성능중심 설계기준으로 변화하고 있는 실정이다. 또한, 콘크리트 재료 및 구조물의 성능 검증을 위하여 재령효과에 따른 콘크리트 강도를 검토할 경우 적절한 모델을 사용하여야 한다. 따라서 이 논문에서는 국내 재료 특성을 반영한 콘크리트 강도발현 상수를 제안하고, 그 적합성을 평가하였다.
