摘 要:箱梁由于抗弯能力强,抗扭刚度大,广泛用于修建城市桥梁、曲线桥和大跨度桥,但它在偏心荷载作用下的扭转畸变行为分析较为复杂。随着箱梁在土木工程领域的应用日益广泛,箱梁的扭转畸变效应越来越受到设计人员的重视。本文以哈尔滨松花江大桥为例,对大跨变截面连续箱梁的扭转、畸变,采用ANSYS进行了有限元分析。
Abstract: Because of having great flexural capacity and torsion rigidity, box girders are widely used in the construction of urban highway, horizontally curved and long-span bridges. But it is complicated to study the torsion and distortion of box girders under the action of eccentric loads. With the extensively using of box girders in the civil engineering field, more and more design engineers pay high attention on the torsion and distortion effects of box girders. Taking the example of the main bridge of Songhuajiang River Bridge at Harbin, the torsion and distortion of long-span continuous bridge with variable cross sections is studied by using the ANSYS finite element analysis software.
