A new method for studying wind engineering of bridges: Large-scale aeroelastic model test in natural wind

Abstract

To overcome the limitations of the existing experimental methods (i.e., wind tunnel test and in-situ measurement) for wind engineering research of bridges, a new experimental method is proposed, i.e., studying the wind-resistant performance of bridges based on large-scale deck sectional models and full bridge aeroelastic models in natural wind. The representative wind field data are offered to briefly verify the feasibility of this experimental method. The Outdoor Experimental Bases for Bridge Wind Engineering of Dalian University of Technology as well as three full bridge aeroelastic models and a large-size steel tower (for deck sectional model and cable aeroelastic model tests) are introduced, and the extensive possible research items are listed. The available sensors and instruments are outlined, which enable many kinds of measurements. The advantages and disadvantages of the newly proposed experimental method relative to the existing ones are commented for deepen the understanding.
