摘　　要：为了研究玄武岩纤维布增强木梁的抗剪性能,通过5组共15根木梁进行两点集中加载静力试验,分析和研究了不同纤维布宽度和层数等因素对木梁和加固木梁抗剪极限承载能力和挠度的影响。结果表明:在木梁受剪区域粘贴玄武岩纤维布能有效提高木梁的刚度、延性和抗剪极限承载能力。并使用ABAQUS软件对玄武岩纤维布加固木梁的抗剪性能试验进行仿真模拟,通过对比模拟结果与试验结果,验证了应用ABAQUS程序对玄武岩纤维布加固木梁进行数值模拟的可行性。In order to study the shear strength of timber beams reinforced by basalt fiber fabric,the effects of different factors such as fiber cloth width and number of layers on the shear ultimate load capacity and deflection of wood beams and reinforced wood beams were analyzed and studied by five groups of 15 wood beams with two-point concentrated loading static tests.The results show that the stiffness,ductility and shear ultimate bearing capacity of timber beams can be effectively improved by pasting basalt fiber fabric in the shear area of timber beams.The shear performance test of basalt fiber cloth reinforced wood beams was simulated using ABAQUS software,and the feasibility of applying ABAQUS program to numerical simulation of basalt fiber cloth reinforced wood beams was verified by comparing the simulation results with the test results.
