ANALYSIS AND DESIGN METHODOLOGY FOR AN FRP CABLE-STAYED PEDESTRIAN BRIDGE

This paper describes the various analysis and design aspects of a fibe r reinforced plastic (FRP) bridge. The design methodology is illustrat ed by describing the steps taken in the design of the first US FRP cab le-stayed pedestrian bridge to be constructed in Lincoln, Nebraska. Th e analysis is made using three dimensional (3-D) macro models of the b ridge to describe its overall behavior under static and dynamic loads. Separate analysis is done to study the local stability of the differe nt structural elements. The orthotropy of the material is taken into a ccount during this analysis. The short term and long term stiffnesses and strengths are evaluated and accounted for in the design process.
