| Description | Journal: Iop Conference Series: Materials Science and Engineering In order to understand the creep effect of Extradosed bridge, the paper adopted four concrete creep calculation models recommended by Chinese, European, American and Japanese specifications, Taking the first concrete Extradosed cable-stayed bridge under operation in Yunnan Province of China as an example, The effect of creep on the displacement and stress of the main beam, and the Cable Tension were calculated. The results show that as for the impact of creep effect on deflection of the main beam of the Extradosed cable-stayed bridge, the absolute value is smaller than that of the continuous rigid-frame bridge with the same span, but it has a relatively great impact on the stress and cable force. This article is proposed that as reserve of stress at the lower edge of the section in non-stayed cable segment area should be increased appropriately, and the safety coefficient of stay cables at the operating stage can be properly increased, and the value recommended by this article is 1.87 |
