FRP加固剪力墙抗冲击性能的研究进展

Research progress of impact resistance of shear wall strengthened with FRP

建筑结构经常承受动荷载的作用,导致受力构件提前退化,降低承载能力甚至发生倒塌,往往受力构件是无法更换的,因此对结构进行加固就变得尤为重要.纤维增强复合材料因其强度高、耐久性好、便于施工等优点,在加固中得到广泛应用.在冲击荷载作用下,对纤维增强复合材料加固钢筋混凝土剪力墙的理论分析、抗冲击性能等方面进行了综述;详细介绍了纤维增强复合材料在钢筋混凝土剪力墙加固中的应用,最后,对纤维增强复合材料抗冲击的研究进行了展望.

Building structures often bear dynamic loads,leading to degradation of the stressed components in advance,reduction of load-bearing capacity and even collapse.Often the stressed components cannot be replaced,so it becomes particularly important to reinforce the structure.Fiber reinforced plastics are widely used in reinforcement because of their advantages such as high strength,good durability and ease of construction.The theoretical analysis and impact resistance of reinforced concrete shear walls reinforced by fiber reinforced plastics under impact load are reviewed.The application of fiber reinforced plastics in reinforced concrete shear wall reinforcement is introduced in detail.Finally,the research on impact resistance of fiber reinforced plastics is prospected.
