采用已被广泛应用的ABAQUS有限元软件, 建立两种复合纤维聚合物——BFRP/GFRP分别加固不同范围的四组“T”形节点模型, 均采用同一低周反复荷载进行抗震效果分析.模拟分析结果表明, ①随着喷射范围的逐渐增加, 梁端承载力和极限变形不断加大, 且滞回环逐渐趋于饱满, 构件的耗能也在增大, 有利于结构抵抗变形; ② 在相同荷载的作用下, 复合纤维材料的弹性模量越高, 其应力增长就越快, 从而越能有效地限制混凝土开裂及其变形, 在节点抗剪方面类似于增加节点整体刚度, 能有效延缓构件的破坏, 使得喷射材料发挥出更大更强的抗剪能力.“,”The ABAQUS finite element software, which has been widely used, is used to establish four groupsof“T”joint models of two kinds of composite fiber polymers-BFRP/GFRP, which are respectivelystrengthened in different ranges.The seismic effect analysis is carried out by using the same low cyclic re-versed load.The simulation results show that: ① With the gradual increase of the injection range, thebearing capacity and ultimate deformation of the beam end increase continuously, and the hysteresis loopstend to be full gradually, and the energy consumption of the components also increases, which is beneficialto the structural resistance to deformation. ② Under the load at the same level, the higher the elastic mod-ulus of the composite fiber material, the faster the stress growth will be, thus more effectively limiting thecracking and deformation of the concrete, which is similar to increasing the overall stiffness of the joint interms of shear resistance, effectively delaying the damage of the component and making the sprayed mate-rial, FRP, exert greater and stronger shear resistance.ABAQUS can simulate the reinforcement effect oftwo FRPS on the structure node area.
