Abstract:	本研究使用超高性能纖維混凝土(Ultra High Performance Fiber Reinforced Concrete, UHPFRC)製成UHPFRC懸臂梁試體，並進行反覆載重實驗，探討其撓曲行為。實驗中設計並製造數支UHPFRC懸臂梁試體，試體設計參數包含：鋼纖維量、鋼纖維種類及複合材料斷面等，採用反覆位移荷載實驗進行評估，調查UHPFRC懸臂梁之抗耐震特性，試體之性能評估參數則包含：初始勁度、強度、韌性、能量吸收力、勁度與強度折減、力量位移遲滯圈、以及開裂模式等。 ;The objective of this study is to evaluate the performance of Ultra High Performance Fiber Reinforced Concrete (UHPFRC) flexural members under cyclic loading. Six cantilever beams are designed and prepared. The design parameters include fiber volume fractions, and locations, types, and amounts of fibers. The performance of the cantilever beams is evaluated using multiple measures, including: initial stiffness, strength, ductility, energy dissipation, hysteretic loop, and cracking behavior. Detailed results are presented in the dissertation.
