Abstract

An accurate model of distributed aerodynamic and aeroelastic pressures on bridge decks is crucial to the stress-level analysis of long-span bridges. This study firstly proposes a framework for modelling distributed aerodynamic and aeroelastic pressures on a bridge deck using the proper orthogonal decomposition (POD), in which the indicial functions are introduced to feature the unsteady components associated with different structural motion and wind turbulence. The POD pressure modes, pressure modal derivatives, distributed aerodynamic and aeroelastic pressures, integrated aerodynamic and aeroelastic force, and force derivatives of a typical twin-box bridge deck are then identified and discussed as a case study.
