After analyzed, it shows that: the enhance of transverse stability by transverse bracing is effective, but the enhance becomes very little when the stability of arc achieving some degree; the transverse seismic response of arch is enhanced by transverse bracing, and the more bracing using influences the beauty of arch and causes the material waste.
在设计时，可通过优化横撑布置、增加横撑数量、增大拱肋刚度等方法来增加拱肋横向的整体刚度，以保证其横向稳定性。然而，横撑在增加横向稳定的同时，也加大了拱的横向整体刚度和质量，提高了拱肋重心，使得拱对横向地震波的响应增大。
The influence of transverse stability and seismic behavior of half-through arch bridge of concrete filled steel tube by transverse bracing is studied, using finite element method.
钢管混凝土拱桥的面外基频较面内基频略低，反映出钢管混凝土拱桥横向稳定问题较为突出，尤其是长大跨度时。
Transverse bracing was installed between the two shafts. Minute vertical and lateral adjuster is built in the nozzle.
喷嘴安装横向和纵向的为调节装置。
And then this thesis analyzes the impact on the stability in detail, such as the side arch and its inclination, transverse brace and diagonal bracing, the invalid suspender and side cable. The conclusions of this thesis provide references for the similar bridges.
