Analysis of technical condition of footbridges over the railways in danger of collapse [PDF]
MATEC Web of Conferences, 2019 The article presents issues related to the maintenance of small engineering structures, such as footbridges over railways. These types of objects, usually are simple both in structure and construction.

Modelling of lateral forces generated by pedestrians walking across footbridges
, 2021 The mechanism which results in the synchronization of people walking across footbridges with the bridges fundamental horizontal frequency is studied. The lateral vibration of a bridge subjected to walking pedestrians is modelled by considering the bridge

Vertical Vibrations of Footbridges Due to Group Loading: Effect of Pedestrian–Structure Interaction
Applied Sciences, 2021 The vibration serviceability of footbridges has evolved from the adoption of a single pedestrian crossing in the resonance condition to load cases in which several pedestrians cross the structure simultaneously.

A Statistical Approach for Modeling Individual Vertical Walking Forces
Applied Sciences, 2021 This paper proposes a statistical approach for modeling vertical walking forces induced by single pedestrians. To account for the random nature of human walking, the individual vertical walking force is modeled as a series of steps and the gait ...

Experimental and Numerical Dynamic Properties of Two Timber Footbridges Including Seasonal Effects
International Journal of Civil Engineering, 2021 This paper deals with experimental and numerical dynamic analyses of two timber footbridges. Both bridges have a span of 35 m and consist of a timber deck supported by two timber arches. The main purpose is to investigate if the dynamic properties of the

Experimental and Numerical Analyses of Timber–Steel Footbridges
Applied SciencesIn addition to traditional building materials, such as steel and concrete, wood has been gaining increasing prominence in recent years. In the past, the use of wood was limited due to its susceptibility to damage by fungi, insects, and temperature. These

INTERVAL SERVICEABILITY ASSESSMENT OF FOOTBRIDGES [PDF]
Proceedings of the XI International Conference on Structural Dynamics, 2020 This paper studies serviceability assessment of footbridges through a non-deterministic approach. The parameters defining pedestrian-induced loading and the structural dynamic properties are characterized through possible ranges of variation. Starting from analytical expressions for the spectral moments of the structural response, the improved interval
