고인성 섬유보강 시멘트 모르터의 휨 피로성능 = Flexural Fatigue Performance of Multiple-Cracking Type HPFRCC

다국어 초록 (Multilingual Abstract)

High performance fiber reinforced cement composite(mortar) shows ultra high ductile behavior in the hardened state, because of the fiber bridging properties. Therefore, a variety of experiments have being performed to access the performance of the materials recently. In this study, a flexural fatigue test was carried out to investigate flexural fatigue behavior and provide basic data for fatigue design. Based on the flexural fatigue test, the fatigue safety of the high performance fiber reinforced cement mortar specimens was estimated. For the fatigue test, 10x10x40cm specimens were designed. A static flexural load test was also performed before the fatigue test to analyze the structural behavior of the specimens. The initiation of fatigue cracks in the specimens could be detected through the history of displacement range. Fatigue limit was predicted Weibull distribution using S-N relationship, and a satisfactory result was obtained.
