Embodiment Construction
[0043] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0044] The first embodiment provided by the present invention is: a method for predicting the nonlinear wind-induced response of a suspension bridge, such as figure 1 shown, including:
[0045] Step S1, setting combined parameters of different reduced wind speeds, different vertical amplitudes and different torsional amplitudes of the main girder section of the suspension bridge; and obtaining various nonlinear aerodynamic time histories of the main girder section under different combined parameters.
[0046] In this step, the CFD numerical simulation platform is used to calculate the n...
