摘要
用试验的方法研究了道路、桥梁等混凝土结构增强用及斜拉索用纤维筋棒的破坏强度.破坏试验结果表明:纤维筋棒的夹持方法非常重要,夹持方法的不同对其破坏强度影响很大.其次,利用载荷距离加权局部分配法则和破坏柱元的概念,运用统计理论计算了纤维筋棒的破坏强度,理论计算与试验数据吻合较好.
The failure of fiber_reinforced plastic rebar (FRP Rebar) used in concrete structures such as roads and bridges as strengthening bars is studied experimentally in the paper. How to grip a FRP Rebar is very important. The experimental results show that different methods of gripping it have great influence on its ultimate strength. In addition, the ultimate strength of a FRP Rebar is calculated by using the statistical failure theory based on the weighting distance local load_sharing rule and the concept of the element of fiber column. The theoretical results are closer to the experimental ones.
