摘要:

为探究钢板-钢筋焊接接头受拉性能及破坏模式,制作10组钢板-钢筋焊接接头试件并对其进行单向拉伸试验。分析了钢筋直径、钢板厚度、钢板宽度和搭接长度对试件承载力和破坏模式的影响以及应力沿钢筋纵向和钢板纵横向的分布规律,并利用ABAQUS软件对试验结果进行有限元模拟。结果表明:钢板宽度为50 mm时,钢板厚度由10 mm增加至12 mm,破坏模式会由钢板撕裂转变为钢筋断裂,且钢板宽度和钢板厚度对破坏模式影响较大; 搭接长度小于等于30 mm时,焊缝会同钢板发生撕裂; 焊接接头承载力随钢筋直径、钢板厚度、钢板宽度和搭接长度的增加而增大,其中钢板厚度对接头承载力影响最大; 钢筋相同测点处应变总体变化趋势为随钢筋直径增大而逐渐减小,其余参数则与之相反; 钢板相同测点处应变总体变化趋势为随钢板宽度增大而逐渐增大,其余参数则与之相反; 沿测试端至固定端方向,钢筋和焊缝上拉应力逐渐减小,钢板上拉应力逐渐增大; 沿钢板横向方向,钢板上应力由其轴心线向两侧边缘逐渐减小; 有限元模拟结果同试验破坏模式和荷载位移曲线吻合良好,有限元模拟方法可靠。

Abstract:

In order to investigate the tensile performance and failure modes of these joints, 10 sets of steel plate-steel bar welded joint specimens were fabricated and subjected to uniaxial tensile tests. The effects of steel bar diameter, steel plate thickness, steel plate width, and lap length on the bearing capacity and failure modes of the specimens were analyzed. Additionally, the stress distribution along the longitudinal direction of the steel bars and both longitudinal and transverse directions of the steel plates was examined, then the test results were simulated by using ABAQUS software. The results indicate that when the width of the steel plate is 50 mm, the thickness of the steel plate increases from 10 mm to 12 mm, and the failure mode changes from steel plate tearing to steel bar fracture, and the width and thickness of the steel plate have a great influence on the failure mode. When the lap length is less than or equal to 30 mm, the weld will tear with the steel plate. The bearing capacity of the welded joint increases with the increase of the diameter of the steel bar, the thickness of the steel plate, the width of the steel plate and the lap length, and the thickness of the steel plate has the greatest influence on the bearing capacity of the joint. The overall change trend of the strain at the same measuring point of the steel bar gradually decreases with the increase of the diameter of the steel bar, while the other parameters are opposite. The overall change trend of the strain at the same measuring point of the steel plate gradually increases with the increase of the width of the steel plate, while the other parameters are opposite. Along the direction from the test end to the fixed end, the tensile stress on the steel bar and the weld gradually decreases, and the tensile stress on the steel plate gradually increases. Along the transverse direction of the steel plate, the stress on the steel plate gradually decreases from its axis to both sides of the edge. The finite element simulation results are in good agreement with the test failure mode and load displacement curve, and the finite element simulation method is reliable.
