| Abstract: | The cable-stayed bridge camber settings are influenced by many factors,and with Donghe Bridge as the example,through GQJS finite element calculation and field measurement,the article analyzed the impact of creep and shrinkage,tensioned age,elastic modulus,unit weight,temperature and other factors on the camber settings,and described the considerations for the camber settings in cable-stayed bridge construction monitoring. |
