Abstract

This study presents that effect of anchor plate on concrete breakout strength was evaluated. The addition of the anchor plate is to improve the concrete breakout capacity for a single anchor system in a thin-walled concrete panel (Insulated concrete sandwich wall panel). In this study, an elasticity-based simplified model was developed and used to predict effect on the anchor plate. Flexural stresses of the plate with respect to the concrete breakout strength obtained from CCD (Capacity Concrete Design) approach were compared with the test results. Through the test results, while the concrete breakout strength was improved due to increment of the width and thickness of the anchor plate, improvement of the strength was steadily declined. In addition, the It was observed that the analytical and experimental flexure of the anchor plate was comparatively in good agreement using the simplified elastic analysis model.

이 연구는 플레이트의 추가가 중단열 외벽 시스템과 같은 얇은 콘크리트 패널에 설치되는 단일 앵커 콘크리트의 파괴 강도에 미치는 영향을 평가하였다. 탄성론 기반의 단순화된 해석모델을 이용하여 CCD(concrete capacity design)이론을 통해 나타난 콘크리트 파괴 강도에 대한 플레이트의 휨 응력을 예측하였으며, 실험을 통해 나타난 플레이트의 휨 응력과 비교하였다. 앵커의 콘크리트 파괴 강도에 대한 실험은 100 mm의 얇은 패널을 대상으로 수행되었으며, 플레이트의 크기는 플레이트의 휨 응력과 항복 응력이 가장 근사값을 갖는 $PL130{\times}9mm$를 기준으로 계획되었다. 실험 결과를 통해, 플레이트의 너비 또는 두께 증가에 의해 콘크리트 파괴 강도는 향상되는 것으로 나타났지만, 콘크리트 파괴 강도의 향상 수준은 지속적으로 감소하는 것으로 나타났다. 또한, 탄성론 기반의 단순화된 탄성해석모델을 이용하여 해석과 실험 결과를 비교했을 때, 콘크리트 파괴 강도에 대한 플레이트의 영향을 비교적 잘 부합하는 것으로 나타났다.
