Determination of Rational Parameters for the Advanced Structure of a Pedestrian Suspension Steel Bridge

Algirdas Juozapaitis, Arnoldas Norkus

Abstract


. High strength cables and steel plates or prestressed rc members (also named as stress-ribbons) usually serve the main load carrying elements of up-to-date pedestrian bridge structures. An application of these elements is prescribed actually by large magnitude of permanent load. However, a realisation of such structures requires many material resources. This investigation presents an advanced structure type for pedestrian suspension bridge created from hot-rolled cable or welded members of finite flexural stiffness. Development of displacements in such structure subjected by symmetric and asymmetric loadings is analysed. A method of stabilising displacements via flexural stiffness variation and its efficiency is considered. Displacement variation and strength of advanced load carrying structure of structure are investigated, the developed analytical expressions for determining inner forces and displacements are presented. An analysis of rational parameters for advanced structure of pedestrian suspension bridge yields expressions for determining the necessary flexural stiff- ness, cross-sectional height and area of load carrying structural elements. A rational primary shape of structure versus ratio of permanent and variable loadings is analysed. A technical-economic efficiency is illustrated via numerical simulation of rational parameters for advanced structure of pedestrian bridge.
