泉州火车站站前大桥桥头堡风载作用分析

该文阐述了:基于刚性模型表面测压风洞试验,得到泉州火车站大桥桥头堡的风荷载体型系数。在此基础上,通过有限元软件ANSYS建立了三维有限元分析模型。计算得到该结构在两个水平主轴方向风荷载下的位移及应力。结果表明该结构在风荷载作用下变形及应力均较小,能够满足规范的相关规定。

Analysis on Wind Load Effect of Zhanqian Bridge Bridgehead of Quanzhou Railway Station

The article sets forth the wind tunnel tests of surface pressure based on the rigid model and obtains the shaped wind load coefficients of the bridgehead of Quanzhou Railway Station Bridge. On this basis, the three-dimensional finite element model is set up by the finite element software ANSYS to calculate the displacement and stress of this structure under the wind load along two horizontal axes. The results showed that the displacement and stress of this structure are smaller under the wind load and can m...
