크리프 예측 영향요인 검토 및 국내 건설현장 콘크리트 배합을 고려한 크리프 예측 모델식 제안 = Investigation on Factors Influencing Creep Prediction and Proposal of Creep Prediction Model Considering Concrete Mixture in the Domestic Construction Field

다국어 초록 (Multilingual Abstract)

Recently, construction technology of RC structures must be examined for creep in concrete. The factors affectingthe creep prediction of concrete and the results of creep in domestic construction field were reviewed. The longer thecreep test period and the higher the compressive strength, the higher the creep prediction accuracy. The higher thecuring temperature, the higher the initial strength development of the concrete, but the difference in the creepcoefficients increased over time. Based on the results of creep evaluation in the domestic construction field and lab.
tests, a modified predictive model that complements the ACI-209 model was proposed. In the creep prediction of realmembers using general to high strength concrete, the test period and temperature should be considered precisely

국문 초록 (Abstract)

최근 RC 구조물의 건설기술에서는 콘크리트의 크리프에 대한 검토가 이루어져야 한다. 본 연구에서는 콘크리트의 크리프 예측 및 국내 건설현장의 크리프 결과에 영향을 미치는 요인을 검토했다. 크리프 테스트 기간이 길고 압축강도가 높을수록 크리프 예측 정확도가 높아졌다. 경화 온도가 높을수록 콘크리트의 초기 강도가 높아지지만 크리프계수의 차이는 시간이 지남에 따라 증가했다. 국내 건설현장 및 실험실에서의 크리프 평가 결과를 기반으로ACI-209모델을 보완하는 수정 된 예측 모델을 제안했다. 일반~고강도 콘크리트를 사용한 실제 부재의 크리프 예측에서는 테스트 기간과 온도를 정확하게 고려해야한다.
