| Abstract: | According to the theory of finite element,based on the structural analysis program-ANSYS,3 D mod- el of Cang'an Road Cable-stayed Bridge had been introduced in detail.Using this model,the vibrational frequency and mode had been calculated.The effect of warping constant to dynamic property had been discussed.It can be re- ferred for aseismatic and wind-resisting analysis of this bridge. |
