Wind Load Analysis of a Truss Bridge at Rifle Colorado
Current AASHTO requirements for pedestrian bridges may prove some historic truss bridges to be under-strength when applying wind loads to simple skeleton models. The Rifle Bridge over the Colorado River at Rifle, Colorado, is a historic steel truss structure that was one of five in a study to analyze actual wind loads on existing structures. This paper discusses the effects of including stiffening elements in 3D models by comparing actual and calculated wind loads. During the six week wind study period, maximum wind loads measured were in excess of 60 mph, which resulted in easily measured strains. Analytical models include the metal deck with asphalt as a stiffening element, which is treated as plate elements with a modulus representative of the composite section. Recommendations for modeling the deck are provided.
