摘要
从实用计算出发，假设竖向荷载作用在斜交变截面悬臂Ｔ梁桥上截面的横向分布，通过取一弹性支承在主梁上的连续变刚度横梁来计算，从而使复杂的空间计算问题转化为平面问题，然后根据每一主梁上所分配到的荷载，利用斜交变截面有限元分析理论来求出其任意截面的内力和变形。
From the view of practical calculation, this paper assumes that transverse distribution of skew cantilever T shaped beam bridge with varying depth under vertical load at any cross section can be calculated by taking a continuous transverse beam with varying stiffness supported elastically on main T shaped beams of the bridge. Thus, the complicated spacious problem can be changed to plane problem. Internal force and deformation at any cross section of every single skew beam can be gained by using the finite element theory of skew beam with varying depth according to the distributed load.
