Rational cross-sectional design and behavioural analysis of the low-sag stressed ribbon pedestrian bridges/Rationale Querschnittsbemessung und Verhaltensanalyse der Fußgänger-Spannbandbrücken mit geringem Durchhang

Abstract

Stress ribbon bridges represent one of the simplest and the most efficient modern bridge constructions used in modern lightweight pedestrian bridges. The article presents an analysis of the stress ribbon bridge behaviour by applying different values of constant loads, assessing the possibilities of using steels and composite materials. The article presents the methodology for the rational cross-section and shape design of the low-sag stressed ribbon structure, based on the rigidity conditions. The article discusses the structure‘s behaviour in asymmetric loads and provides recommendations for Design.
