철근콘크리트보의 동결융해 경험에 따른 반복하중하에서의 이력특성
Hysteretic Behavior of RC Beams Exposed to Freezing and Thawing under Cyclic Loadings
초록
일반적으로 철근콘크리트 건축물은 외부의 기후에 노출되어 있어 겨울에서 이른 봄까지 동결과 융해의 반복적인 작용에 영향을 받는다. 이러한 동결융해 작용은 콘크리트의 균열을 발생시키거나 콘크리트 표면의 박리를 일으켜 내구성 저하의 원인이 된다
Generally, reinforced concrete structures exposed to the outside temperature are affected by freezing and thawing process during winter and early spring. These freezing and thawing process can lead to the reduction in durability of concrete as cracking or surface spalling. This paper is to study the hysteretic behavior of RC beams exposed to freezing and thawing under cyclic loadings. To compare the difference in hysteretic behavior of RC Beams, limited tests were conducted under different types of damage and freezing and thawing cycles. For this purpose, six specimens were tested. It is thought that experimental results will be used as basic data to evaluate hysteretic behavior of RC beams exposed to freezing and thawing.
