摘要
斜拉-连续协作体系桥自振周期短,刚度大,是介于连续梁桥与斜拉桥之间的桥型。协作体系有助于提高桥梁的力学性能,也有助于施工技术的提高,钢筋混凝土梁段与钢梁连接处内力有所变化,可以考虑按材料的特性进行布置,这种结构可以提高桥梁承载能力。斜拉-连续协作桥自振频率较为密集,振型频率相邻。
The diagonal-continuous collaborative system bridge has a short self-oscillation period and high stiffness,and is a bridge type between the continuous girder bridge and the diagonal bridge.The collaborative system helps to improve the mechanical properties of the bridge and also the technology.The internal forces at the connection between the reinforced concrete girder section and the steel girder vary and can be considered to be arranged according to the properties of the material,and this structure can improve the load carrying capacity of the bridge.Diagonal-continuous collaborative bridges are more dense in self-vibration frequencies,with adjacent vibration frequencies.
