When the in-plane stability of such arch is in control of the bridge design, Transverse wind load has a little influence on the stability factor and ultimate load carrying capacity.
当此类拱桥出现面内稳定控制设计时，横向风载的作用对拱桥的稳定系数和极限承载力影响较小。
Y - brace has the least effect on the deformation of transverse beam and theY - braced frame has the highest load - carrying capacity.
同时Y形支撑对框架横梁的变形影响最小，极限承载力也最高。
