给出了以芳纶纤维增强复合塑料AFRP作为预应力筋的高强混凝土梁的弯曲特性及延性的试验结果 ,并提出用一个综合考虑强度与能量等因素的总体因子作为定义AFRP预应力混凝土梁的延性指标。
The experimental results of flexural behavior and ductility of high strength concrete beams with aramid fiber reinforced composite plastic (AFRP) as prestressing tendons are presented. An overall factor that takes strength and energy into account is proposed as the definition of the prestressing force of AFRP prestressed concrete beams Ductility index.
