针对城市高架桥项目中的大悬臂倒T形预应力盖梁,以实际工程为研究对象,分析中、美、欧三种规范的抗剪承载力公式,以不同标准的计算公式为基础,对工程实际预应力盖梁尺寸进行研究,验证倒T形盖梁牛腿部位的配筋形式,为大悬臂倒T形预应力盖梁的设计与应用提供借鉴.
Study on Shear Bearing Capacity and Reinforcement Scheme of Inverted T-shaped Bent Cap Corbel
In view of the large cantilever inverted T-shaped prestressed bent cap in the urban viaduct project,taking an actual project as the research object,the shear bearing capacity formulas of three specifications in China,the United States and Europe are analyzed.Based on the calculation formulas of different standards,the actual prestressed bent cap size is studied,and the reinforcement form of the inverted T-shaped bent cap corbel is verified,which provides reference for the design and application of the large cantilever inverted T-shaped prestressed bent caps.
