Dynamic Buffeting Response Analysis of High Pier and Long Span Continuous Rigid Frame Bridge with Stochastic Wind Field
The fluctuating wind field is simulated for digital by using the stationary Gauss processes, which Kaimal spectrum and Panofsky spectrum is used to the simulation of wind target spectrum with different direction and speed. According to Davenport quasi-steady buffeting force model formula, the time-history of wind velocity is converted to Buffeting force time history, which are applied to the Structure model node, combined with ANSYS for long-span continuous rigid frame bridge buffeting response analysis dynamic simulation. Taking a high pier and long span continuous rigid frame bridge as an example, analyzes dynamic buffeting response of the bridge under the action of the stochastic wind field, which as the guidance of high pier and long span continuous rigid frame bridge design work, practice has proved that the method is simple, reliable, also can be a way that dynamic analysis of buffeting response of large span bridge or tower structure under the action of stochastic wind field.
