摘要:
通过对竖向荷载作用下的矩形和箱形2种截面形式的预应力混凝土曲线转换梁进行的试验研究,分析了不同截面形式的曲梁对转换结构受力性能的影响.研究表明,曲梁内的扭矩不容忽视,但只要设计合理,预应力曲线转换梁同样具有良好的工作性能和破坏形态.最后还提出了预应力曲线转换梁结构的一些设计建议.
Abstract:
On the basis of experiments on prestressed concrete curved transfer girders of box and rectangular sections under vertical load, this paper analyzes the effects of different section types of curved beam on the mechanic property of transfer structure. The results of study show that the torque presenting in curved beams not to be overlook. If design is rational, the prestressed curved girder structures still have good working behavior and sound failure patterns. Finally, some design suggestions for prestressed curved girder structures and things like these are presented.
