Abstract

This paper demonstrates that polyester rope has potential as an alternative to steel cable for pedestrian suspended bridges (for spans up to 50 m) in rural parts of the developing world. The specific objectives are to show that (1) polyester is the most viable synthetic rope material for this application, (2) pedestrian, polyester-rope suspended bridges can meet static dead and live load strength and serviceability criteria, and (3) different design strategies than those used to design steel-cable bridges are required to take advantage of polyester rope's low material stiffness. To fulfill the first objective, cost and material properties of synthetic rope materials are compared. To satisfy the second and third objectives, a preliminary design for a 1-m wide, 46-m span pedestrian, polyester-rope suspended bridge is presented and compared to a steel-cable design. Calculations were performed using an approximate theory for flat cables and with a geometric nonlinear static finite element solver.
