Abstract

Recently, extreme climate change has been occurring globally not only in the simple form of temperature increases but also in a wide range of extreme climatic events, such as abnormal drought conditions and frequent typhoons. In addition, climate change is delaying the construction period of concrete structures, increasing related economic losses. Forcing construction projects for completion without considering climate change is leading to concrete quality deterioration, poor quality constructions, and consequent casualties and property damage. Therefore, to address these problems and provide a countermeasure to climate change, the present study selected wind speed, and sunlight exposure time as the most important curing conditions among the climate factors affecting concrete structures and examined their effects on the curing and durability of concrete structures. In addition, for the analysis of the experimental results, this study proposed a process of performance based evaluation (PBE) of concrete strength and durability using a method of Satisfaction Curve (SC) generation.

최근 국내의 경우 폭염, 폭우, 한파, 폭설, 태풍과 같은 기후변화가 심각하게 발생하고 있다. 이러한 극심한 기후변화로 인하여 건설현장에서 구조물의 공사 진행기간이 연장되어 그로 인한 경제적 손실을 초래하고, 기후변화를 고려하지 못한 상황에서 무리한 시공을 하여 콘크리트의 품질저하로 인해 부실시공의 원인이 되고 있는 실정이며 이로 인하여 인명피해와 재산피해도 발생한다. 따라서 본 연구에서는 이러한 문제점들을 해결하고 기후변화 대응책을 마련하기 위하여 콘크리트 구조물에 영향을 미치는 다양한 기후인자들 중 가장 중요한 풍속과 일조시간 경화조건을 선정하여 콘크리트 구조물의 양생과 내구성 영향을 검토해 보았다. 또한 실험결과를 분석하는 방법으로는 만족도 곡선 작성방법을 사용하여 콘크리트 강도와 내구성능에 관한 성능중심형평가(PBE: Performance Based Evaluation)절차를 제시하고 하고자 한다.
