Abstract

E-dong Yangtze River Highway Bridge is a compound double Tower Double Suspension Cable stayed bridge with a main-span of 926m. it has very distinctive geometric nonlinearity, which features as a long span, a high Tower, a soft construction, etc. in order to analyze how the geometric nonlinearity will affect the live load effect of large-span cable stayed bridge, we adopted the experimental results of the static experiments of the E-dong bridge to do a comparative analysis, during which all the calculation was based on the limited Factor theory. And the results showed that, the nonlinear results fit much better with the actual response of large-span cable stayed bridge, while the linear results produced a big difference.
