Structure-to-Human Interaction (H2SI): Pedestrian Response to Oscillating Footbridges and Considerations on Their Structural Control and Health Monitoring

Infrastructures
This review paper investigates the current state of research on structure-to-human interaction (S2HI) in the monitoring and control of cyclo-pedestrian footbridges, focusing specifically on the biodynamic effects of oscillations on pedestrians.

Measured Dynamic Properties for FRP Footbridges and Their Critical Comparison Against Structures Made of Conventional Construction Materials

Composite Structures, 2019
The related paper reports new experimental data for dynamic properties (i.e. modal mass, natural frequency and damping ratio) of eight FRP composite footbridges in Europe, which helps to resolve the weakness in knowledge and understanding of dynamic ...

Experimental Tests and Numerical Analyses for the Dynamic Characterization of a Steel and Wooden Cable-Stayed Footbridge

Infrastructures, 2023
Vibrations are an issue of increasing importance in current footbridge design practice. More sophisticated footbridges with increasing spans and more effective construction materials result in lightweight structures and a high ratio of live load to dead ...

Uncertainty-Based Approaches for the Lateral Vibration Serviceability Assessment of Slender Footbridges

Structures, 2021
Slender footbridges with long spans and light materials may lead to serviceability problems in lateral vibrations due to walking pedestrians. The phenomenon, known as the “lock-in effect” occurs when the number of pedestrians on the footbridge reaches ...

Assessment of the Lateral Vibration Serviceability Limit State of Slender Footbridges Including the Postlock-in Behaviour

Applied Sciences, 2020
The lateral vibration serviceability of slender footbridges has been the subject of many studies over the last few decades. However, in spite of the large amount of research, a common criterion has not been set yet.

FRP bridges in Poland: state of practice [PDF]

Archives of Civil Engineering, 2021
The state of the art in the field of composite polymer bridges in Poland is presented below. Such bridges were built from 1999. Some of them are fully composite polymer structure. Others are developed as hybrid structure. There are two kind of structures:

Evaluation of the Equivalent Moving Force Model for Lightweight Aluminum Footbridges in Simulating the Bridge Response under a Single-Pedestrian Walking Load

Engineering Proceedings, 2023
Due to its high strength-to-weight ratio, corrosion resistance, extrudability, and recyclability, there is a growing demand for the use of aluminum for sustainable bridge constructions, especially for footbridges.
