Effect of Footfall Induced Vibration on Footbridges
This paper presents the outcomes of investigating the dynamic behaviour experienced by composite footbridges and concrete footbridges when subjected to footfall induced vibration incurred by walking pedestrians. The study focuses on three set of varying parameters including bridge’s deck thickness, span length and width of footbridge. Models are generated and analysed using finite element method. Dynamic responses obtained from the footfall analysis are expressed in term of vertical displacements and accelerations. Data are tabulated and evaluated based on different parameters incorporated; meanwhile comparisons are made between concrete and composite footbridges. It was found that for both composite and concrete footbridges, the displacement and acceleration decrease exponentially with the increase of deck thickness. They also show decreasing trend with the increase of span length. Besides, an increase in displacement and acceleration is observed with the increase of footbridge width.
