摘要
由单向纤维组成的FRP片材具有缺陷少、不易形成疲劳裂缝以及疲劳强度高等特点。上世纪80年代末,国外开展了FRP片材加固混凝土构件的疲劳性能研究,而国内的有关研究工作则始于上世纪90年代末。本文主要介绍国内外关于FRP片材加固混凝土构件疲劳性能的试验研究、仿真分析与设计建议等方面的最新研究进展。
FRP sheets made of unidirectional fiber have advantages of few flaws, high crack resistance and fatigue strength At the end of 1980＇ s, the fatigue behaviors of concrete members strengthened with FRP sheets were studied by overseas researchers, while the corresponding research in China were carried out firstly at the end of the 20th century. Latest studies on fatigue behaviors of concrete members strengthened with FRP sheets are introduced in this paper, including experiments, simulation analysis and design suggestions, etc
