我国的预应力混凝土V形支撑桥梁

Pre-stressed Concrete V-shape Strut-framed Bridge in China

介绍V形支撑桥梁的优点 ,即结构受力比较合理 ,结构刚度大大提高 ,以及结构构件尺寸减小 ,降低桥高 ,造价经济 ;也介绍了其不利的一面。列出国内外V形支撑桥梁的一些参数 ,并对国内V形支撑结构类型中有代表性的桥梁作了叙述。文章最后对结构体系、梁长、梁的截面、斜撑交角。

This paper introduces to the advantages of V?shape strut?framed bridge, in terms of structure force distribution, rigidity, sizes and construction cost, as well as disadvantages A number of parameters of the V?shape strut?framed bridges both at home and abroad are given, together with some descriptions of typical V?shape strut-framed bridges in China Analysis and discussions are made of the structural system, length and section of the beam, angle of sway brace, height of the beam, material index and etc
