A Study on Existing Evaluation Method and TES Method about Toughness of Fiber Reinforced Concrete

섬유보강콘크리트의 인성에 대한 기존평가방법과 TES 기법에 관한 연구

Fiber reinforcement can significantly improve the properties of concrete. Particulary, toughness or energy-absorbing ability of fiber reinforced concrete is frequently higher than that of unreinforced concrete. Toughness is a measure of energy absorption capacity and used to characterized fiber reinforced concrete's ability to resist fracture when subjected to static, dynamic and impact loads. However, the current standard methods of characterizing the toughness of fiber reinforced concrete have proven to be some inadequate and problems and have caused a great deal of dissent and confusion. This study research some of the inadequate and problems with these toughness measurement methods and proposes the evaluation method for Fiber Reinforced Concrete toughness.
