【摘要】 利用大型有限元分析软件ansys对庐铜高速公路段某混凝土箱形梁桥进行计算,对比分析箱梁桥在跨间设置与不设横隔板情况下的箱梁横截面正应力、抗扭刚度、以及截面变形等因素的变化,分析结果显示加设横隔板后,箱梁受力有明显改善。更多还原

【Abstract】 This paper is to analyze and contrast normal stress of box girder cross section, torsion stiffness and deformation of cross section in the condition of setting diaphragm or not through computing concrete box girder bridge on Lu-Tong Freeway using FEM software ANSYS. The result is that the performance of box girder bridge becomes better by setting intermediate diaphragm.更多还原
