Abstract

In the modern era, the demand for lightweight footbridges has grown significantly. However, this trend introduces new challenges related to the dynamic behaviour of such structures, especially under pedestrian-induced loading. This paper investigates the dynamic response of footbridge decks, focusing on the effects of vibration, pedestrian loading, and design considerations. Through a detailed analysis of a simply supported footbridge, we evaluate natural frequencies, critical ranges, and acceleration responses under varying pedestrian densities. The results emphasize the need for careful consideration of dynamic effects in the design phase to ensure pedestrian comfort and structural safety.
