There is little research on the wind-induced lateral torsional buckling stability problem for long-span concrete filled
steel tube arch bridge.Through a practical bridge,the stability of CFST arch bridge sufered wind load was analyzed.The resuits show that the stronger the wind rapidity is,the smaler the coeficients of stability is,and weak wind have little influence on the stability,but the strong wind afects greatly on the stability of the structure,and the nonlinear considered under the analysis of stability of CFST arch bridge in construction is better,and the material nonlinear has a greater influences on the stability of the bridge than the geometrical nonlinear does.
