碳纤维布对于限制设备破坏以及不合格的钢筋混凝土构件的破坏具有很大优势,已经被广泛地用于建筑物抗震的局部修复。通过系统评估各种被加固构件的抗力机理和握裹力作用,探讨了抗震修复/增强技术有关的设计问题和细节准则,包括:屈曲、剪力、互搭接头承载力、塑性铰性能以及与植入钢筋有关的变形能力和包裹应变能力。在循环荷载下采用碳纤维布加固钢筋混凝土梁/柱的已公布的试验数据库,被作为评估细节准则和校准设计下限的参考。同时也对提升设计策略,采用纤维加固控制结构变形的标准进行了探讨。
Carbon fiber cloth has great advantages in restraining the destruction of equipment and failure of unqualified reinforced concrete members and has been widely used in the local repair of earthquake-resistant buildings. By systematically evaluating the resistance mechanism and the holding force of various reinforced members, the design problems and details of the seismic strengthening / strengthening technology are discussed, including the buckling, shearing, the bearing capacity of the lap joint, the plastic hinge performance, Implantable reinforcement-related deformability and package strain capability. Released test databases reinforced with carbon fiber sheets under cyclic loading for reinforced concrete beams / columns are used as a reference for assessing detail guidelines and calibration design limits. At the same time, it also discusses the ways to improve the design strategy and adopt the fiber reinforcement control structure deformation.
