摘要(Abstract):

悬臂梁或挂梁的牛腿结构由于截面高度显著减小 ,其工作条件比正常形状构件的工作条件要不利得多 ,密集的钢筋使牛腿的构造和施工变得复杂。为解决上述问题 ,给出了一种沿桥面悬臂端水平方向呈齿状分布的斜牛腿用以支承挂梁 ,并给出了这种新型牛腿的设计方法和原则 ,可用于实际工程
A new type of bracket bevelled bracket is put forward to improve the stress state of the bracket. The complicated construction of the common bracket is overcome by using the bevelled bracket. The design method and principle are described in detail. The bevelled bracket is used in the project.
