Assessment of human-induced vibrations of a cable-stayed footbridge

MATEC Web of Conferences, 2018
The primary purpose of this research is the evaluation of human-induced vibrations of a cable-stayed footbridge. The cable-stayed pedestrian bridge with total length of the span equal to 46.90 m located in Czestochowa (Southern Poland) was chosen as a ...

Understanding pedestrian bridge usage considering perception and socio-demographic characteristics of the road users in Dhaka city

Transportation Research Interdisciplinary Perspectives
Walking often involves crossing a road, where the chance of vehicle–pedestrian conflict increases. Footbridges are one of the engineering instruments that offer safety for pedestrians during road crossing avoiding any physical conflicts with pedestrians.

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

City of Skywalks: Exploring Hong Kong’s Public Space and Power of Discourse from Footbridges

Social Sciences, 2022
As a public space and building, the footbridge is not just a physical concrete building but also carries people’s life experiences and beliefs. In Hong Kong, however, footbridges are a joint product of the government and property developers to control ...

Effects of Vertical Ground Motion on Pedestrian-Induced Vibrations of Footbridges: Numerical Analysis and Machine Learning-Based Prediction

Buildings, 2022
Current codes and guidelines for the dynamic design of footbridges often only specify the pedestrian-induced excitations. However, earthquakes may occur during the passing stage of pedestrians in earthquake-prone regions.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

Structural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...
