Buffeting Time-Domain Analysis of Long-Span and Slender Suspension Bridge with a Steel Truss Stiffened Girder

Abstract:

Consideration of natural wind related features, improved use of the harmonic synthesis, along with a high degree of change Simiu spectrum and Lumley-Panofsky spectrum as the goal of full-bridge stochastic wind field were simulated, generating a bridge structure of discrete points of vertical and horizontal wind pulse of time. Carried on the simulation using large universal finite element ANSYS, and the overall evaluation structure’s geometry misalignment, the host cable bridge tower wind load, the effective wind angle of attack’s influence, has calculated of the beam self-excited forces and obtained the long-span and slender suspension bridge with steel truss stiffened girder buffeting response result.
