摘要
提出将预应力混凝土矮肋T梁应用于小跨径桥梁。以20 m跨径简支梁桥为例,对矮肋T梁截面效率,横隔板设置特点进行了分析,并采用解析法和空间有限元法进行横向分布系数分析计算。分析表明,矮肋T梁可应用于小跨径桥梁上部结构。
T-shaped prestressed concrete beam with low web applied to the small-span bridge is intro- duced here. Taking 20m simply supported beam for example, section efficiency and transverse dia- phragm was analyzed, then transversal distribution factor was calculated by analytic method and finite element method. The analysis approves that, T-shaped beam with low web can be applied to small- span bridge.
