【摘要】：为量化面板结构形式对正交异性钢桥面板疲劳性能的影响,以军山长江大桥钢箱梁正交异性板为例进行研究。采用有限元分析软件ANSYS建立4节段钢箱梁仿真分析模型,研究采用5种面板结构形式时正交异性板各疲劳构造细节的最不利应力幅和疲劳寿命系数。研究结果表明:面板刚度增加对面板开裂构造疲劳性能改善作用最大,对加劲肋开裂构造疲劳性能改善作用次之,对横隔板开裂构造疲劳性能改善作用最小;与增加面板厚度相比,采用钢-混组合桥面结构可以大幅降低正交异性板各构造细节疲劳应力幅,提高其疲劳寿命,这一点值得进一步深入研究。
[Abstract]:In order to quantify the effect of panel structure on the fatigue properties of orthotropic steel bridge slabs, the orthotropic plate of steel box girder of Junshan Yangtze River Bridge is studied by taking the orthotropic plate of steel box girder of Junshan Yangtze River Bridge as an example. The finite element analysis software ANSYS is used to establish the simulation analysis model of 4-segment steel box girder. The most unfavorable stress amplitude and fatigue life coefficient of orthotropic plate fatigue structure details are studied when five kinds of panel structures are used. The results show that the increase of panel stiffness has the greatest effect on the fatigue properties of panel cracking structures, followed by the improvement of fatigue properties of stiffened ribs cracking structures, and the least effect on the fatigue properties of transverse partition cracking structures. Compared with increasing the thickness of panel, the fatigue stress amplitude of orthotropic plate can be greatly reduced and the fatigue life of orthotropic plate can be greatly reduced by using steel-concrete composite bridge deck structure, which is worthy of further study.
