3D‐printed concrete footbridges: An approach to assess the sustainability performance

open access: yesStructural Concrete, 2023
Digital fabrication with concrete (DFC) is fast becoming an attractive alternative for components (i.e., façades, urban furniture) and structural typologies (i.e., short‐span footbridges, columns, floor systems) for which complex geometries derived from ...

Uncertainty quantification and propagation of crowd behaviour effects on pedestrian-induced vibrations of footbridges

open access: yesMechanical systems and signal processing, 2022
11 The reliable prediction of pedestrian-induced vibration is essential for vibration 12 serviceability assessment and further vibration mitigation design of footbridges.

Modal Parameter Identification and Comfort Assessment of GFRP Lightweight Footbridges in Relation to Human–Structure Interaction

open access: yesJournal of Composites Science, 2023
With the emergence of slimmer footbridges and the introduction of lighter materials, the challenge of vibrational comfort assessment becomes more and more relevant. Previous studies have shown that each pedestrian will act both as an inducer and a damper,

Viscoelastic damper for vibration mitigation of footbridges

open access: yesIOP Conference Series: Earth and Environment, 2023
Footbridges are among long-span light-weight structures that because of their low damping ratio are susceptible to vibration. Excessive vibration in footbridges usually occurs when they are subjected to rhythmic dynamic loads caused by human activities ...

Sensitivity Analysis for Pedestrian-Induced Vibration in Footbridges

open access: yesBuildings, 2022
This paper aims to provide a novel insight into the influence of uncertainties in system- and pedestrian-induced load parameters on the vibration response of footbridges. The study begins with a sensitivity analysis for the vertical vibration response of

Shear Lag Effects on Pedestrian-Induced Vibration and TMD-Based Vibration Control of Footbridges

open access: yesStructural Engineering International, 2022
The shear lag effect (SLE) is one of the vital mechanical characteristics of structures with thin-walled box sections. While most existing studies of the SLE focus on the static response of footbridges, pedestrian-induced vibration deserves more ...

Visualization of crowd synchronization on footbridges [PDF]

open access: yesJournal of Visualization, 2009
This paper proposes a framework for the visualization of crowd walking synchronization on footbridges. The bridge is modeled as a mass-spring system, which is a weakly damped and driven harmonic oscillator. Both the bridge and the pedestrians walking on the bridge are affected by the movement of each other.

Serviceability analysis for human-induced vertical vibration on pedestrian structures

open access: yesRevista UIS Ingenierías, 2022
Civil engineering structures such as grandstands, slabs, footbridges and staircases have reported unacceptable vertical vibration when they are affected by human activities. Even when most of these structures are designed according to current guidelines

Vibration reduction of footbridges subjected to walking, running, and jumping pedestrian

open access: yesJournal of Vibration and Control, 2022
In this paper, the performance of vibration absorbers in reducing the vertical deflections of the footbridges subjected to human activities is studied. The vertical component of the pedestrian force during walking, running, and jumping is simulated as a ...

Shell-supported footbridges

open access: yesCurved and Layered Structures, 2020
Architects and engineers have been always attracted by concrete shell structures due to their high efficiency and plastic shapes. In this paper the possibility to use concrete shells to support footbridges is explored. Starting from Musmeci’s fundamental
