组合桁梁节点剪力连接件受力性能试验研究
|
摘要
组合桁梁桥是一种新型的桥梁结构形式,具有易于维护、造价合理、承载能力高等优点。为了使钢桁梁与混凝土梁这两种不同材料性质的结构能够协同工作,整体受力,在钢桁梁与混凝土梁结合部位即节点区设置剪力连接件。近年来,剪力连接件随着各式组合结构的发展和应用,得到了长足的发展。
论文首先介绍了组合桁梁桥及其节点的发展、应用和研究现状,然后介绍了剪力连接件的发展概况及研究现状和常用剪力连接件的受力特点、破坏形态、承载力计算公式以及研究方法等内容,最后针对兰新二线特大桥采用的PBL剪力连接件分别进行了拔出试验研究,并将模型试验与非线性仿真分析相结合,主要开展了以下几方面的工作：
1)详细介绍了拔出试验模型的设计、制造、试验方法及测试内容。
2)采用有限元分析软件对PBL剪力连接件的拔出试验进行仿真模拟,并在分析中考虑材料非线性和接触非线性,较为真实的反应剪力连接件的受力状态。同时分析了有无贯穿钢筋、钢筋直径、钢板孔径、混凝土强度等参数对PBL剪力连接件力学性能的影响。
3)对3组PBL剪力连接件拔出试验结果进行分析,并与有限元分析结果进行对比分析,结果表明二者吻合良好。将本次试验结果同以压应力为背景应力的推出试验的结果对比,表明背景应力为拉应力会降低剪力连接件的承载能力。
The composite truss-beam bridge is one of somehow new structures of bridge, and it is provided with easy maintaining, reasonable cost and high carrying capacity. The shear connectors are set up in the joint zone of steel truss girder and concrete beam In order to make the steel truss girder and concrete beam with different materials and different structures can cooperative work.In recent years, the shear connectors obtained the considerable development with the development and application of kinds of composite structures.
This thesis first introduces the development, application and research status of the composite truss-beam bridge, and then introduces development situation and research status of the shear connectors and the stress characteristics, failure mode, bearing capacity formula and research method of several different types of shear connectors in common use, and at last carried out the pullout test research of the PBL shear connectors used in the Lanzhou-Xinjiang Double Lines large bridge, in addition, combined the model test and nonlinear simulation analysis. This paper mainly carried out the following aspects of work:
1) Introduce the design, manufacture, experimental method and test content of the model of the pullout test.
2) Use finite element analysis software to simulate the pullout test of the PBL shear connectors. In the analysis, consider the material and contact nonlinearity, and react the forced state of the shear connectors reality and at the same time analysis the mechanical properties affect of whether there are throughout reinforcements, reinforcement diameter, diameter of orifice in the steel plate and concrete strength to the PBL shear connectors.
3) Analysis three groups of pullout test of the PBL shear connectors and compare to the result of simulation analysis. The result show they are good agreement with each other. Compared with the results of the pull out and push out, it shown that the background stress is tensile stress will reduce the carrying capacity of the shear connectors.
