钢–混组合梁桥单钉剪力连接件抗剪性能研究
Study on the Shear Performance of Single Nail Shear Connectors for Steel-Mixed Girder Bridges
摘要: 为研究单个栓钉剪力连接件在实际工程当中应用时的剪切性能，以某地区在建波形钢腹板钢–混组合梁桥为工程背景进行抗剪性能研究，采用有限元建模的方法，在钢箱梁与混凝土板的连接部位建立局部模型，结合实际工程进行栓钉连接件的仿真推出试验，并将荷载位移曲线结果与经典理论曲线进行对比，结果吻合度高，验证了建模的正确性。在此基础上，探究钢材强度、混凝土强度、栓钉直径、栓钉长度对栓钉抗剪性能的影响，研究发现，随着增强不同因素，对于栓钉抗剪承载力有不同程度的增加，其中栓钉直径对抗剪承载力影响最大，栓钉长度对抗剪承载力影响最小。
Abstract: In order to study the shear performance of a single nail shear connector in actual engineering, the research on the shear performance of the project background is based on the shear performance of the application of wave-shaped steel abdomen-mixed combination beams in a certain area. Methods to establish a local model at the connection parts of the steel box beam and the concrete board, combine the actual project to perform the simulation of the connection parts of the nail connection, and compare the result of the load displacement curve with the classic theoretical curve to verify the correctness of the mold. On this basis, the effects of exploring the effects of steel strength, concrete strength, bolt diameter, and nail length on the anti-shear performance of nails. Research has found that with the increase of different factors, it has to vary degrees of enhancement of the carvings and carriers of the nails. Among them, the diameter of the dwarf is the most impact on the shear capacity, and the length of the nail length confrontation is the minimum effect.
