| 中文摘要: |
| 通过利用拉拔试验和梁式试验得到的纤维聚合物筋与混凝土粘结性能的试验结果，探讨了混凝土强度、锚固长度、纤维聚合物筋直径、混凝土浇筑深度对粘结性能的影响，比较了纤维聚合物筋混凝土与钢筋混凝土的粘结性能，分析了纤维聚合物筋与混凝土之间的应力传递机理。最后，提出了可用于指导设计的计算纤维聚合物筋锚固长度的公式。 |
| 英文摘要: |
| The bonding properties of fiber reinforced polymer(FRP) rebars in concrete are experimentally studied through direct pullout and beam tests.The effects of concrete compressive strength,embedded length reinforcement diameter as well as concrete cast depth on bonding properties are investigated.The mechanism of the stress transferred from FRP rebars to concrete is analyzed.Finally,the design guideline for calculating the anchorage length of FRP rebars is recommended. |
