| Abstract: | Analysis of temperature effect on complete bridge state of an extradosed cable-stayed bridge by using the finite element software midas civil.According to the features of the extradosed cable-stayed bridge,it reveals the law of the main beam deformation,cable force and the stress of the main beam which is act by the temperature rising and reduction of the overall structure,the different temperature between the beam and cable,temperature gradient of the grider.The analytic result can offer a reference for the designment of the similarity type of multi pylon extradosed cable-stayed bridge. |
