Following a series of catastrophic bridge failures, the adverse effects of wind loading on bridges has become a widely discussed topic in the realm of bridge design and research. Currently however, the majority of research focuses on the contribution of wind in long span bridge design. This is primarily because long span bridges have a greater inherent tendency to become aerodynamically unstable. Nonetheless, wind can also contribute to the shear and moment of short span bridges, thereby influencing the limit state of various components in these short span bridge systems. To narrow this scope, the following presentation focuses specifically on the contributions of wind to the shear and moment of slab and girder bridge decks. These contributions are quantified by a model that calculates the shear and moment due to wind loads for a number of variable parameters including angle of impact, bridge height, span length, and deck thickness. Ultimately, it is found that angle of attack has the greatest impact on moment, while span length has the greatest impact on shear about center span.
