项目摘要
The use of the non-corrodible fibre reinforced polymer (FRP) bars to reinforce concrete structures built in harsh environments, such as bridges and parking garages is beneficial to avoid the costly steel-corrosion problems. In North America, a large number of parking structures and industrial buildings is constructed using flat plate system in which concrete slabs are directly supported on columns. The most critical element in such structural system is the slab-column connection where punching shear stresses are the largest. Punching shear failures are usually brittle, sudden and catastrophic in nature and should be avoided. Since FRP bars have linear-elastic behaviour till failure with low stiffness and reduced compressive strength, there are concerns regarding the ductility performance, shear capacity and the integrity of such joints when FRP bars are used, especially under seismic loads. Very limited to no data is available on that topic.
使用非腐蚀性纤维增强聚合物(FRP)钢筋来加固在恶劣环境中建造的混凝土结构,例如桥梁和停车场,有利于避免代价高昂的钢筋腐蚀问题。在北美,大量的停车场结构和工业建筑使用平板系统,其中混凝土板直接支撑在柱上。板柱节点是此类结构体系中最关键的节点,其冲切应力最大。冲剪破坏通常是脆性的、突然的和灾难性的,应该避免。由于FRP筋具有线性弹性行为,直到失效,刚度低,抗压强度降低,因此当使用FRP筋时,特别是在地震荷载下,人们担心这种接头的延性性能,抗剪能力和完整性。关于这一主题的数据非常有限或没有。
