Study of pedestrian-induced vibrations on timber footbridges

Maderas: Ciencia y Tecnología, 2014
In Brazil, studies about pedestrian-induced vibrations on footbridges have been carried out since the early 1990s, for concrete and steel footbridges. However, there is no record of such studies and the Brazilian Standard NBR 7190 (1997) for the design ...

Vision-Based Methodology for Characterizing the Flow of a High-Density Crowd on Footbridges: Strategy and Application

Infrastructures, 2020
Obtaining pedestrian trajectories by a vision-based methodology is receiving increasing attention in the literature over recent decades. Within the field of study of human-induced vibrations on footbridges, practical challenges arise when collecting the ...

Neuroprotective Effects of Senecio brasiliensis Extract Against Chlorpyrifos‐Induced Neurotoxicity and Oxidative Stress in Drosophila melanogaster

Basic &Clinical Pharmacology &Toxicology, Volume 139, Issue 3, September 2026.
ABSTRACT Chlorpyrifos (CP) is an organophosphate insecticide that induces neurotoxicity through acetylcholinesterase (AChE) inhibition and redox imbalance, raising environmental and occupational health concerns. Plant‐derived compounds from Senecio brasiliensis, native to the Pampa biome, offer multitarget therapeutic potential.

Interpolation categories for conformal embeddings

Proceedings of the London Mathematical Society, Volume 133, Issue 3, September 2026.
Abstract In this paper, we give a diagrammatic description of the categories of modules coming from the conformal embeddings V(slN,N)⊂V(soN2−1,1)$\mathcal{V}({\mathfrak{sl}}_{N},N)\subset \mathcal{V}({\mathfrak{so}}_{{N}^{2}-1},1)$. A small variant of this construction (morally corresponding to a conformal embedding of glN${\mathfrak{gl}}_{N}$ level N ...

Evaluating vibrations on a small-scale model of a timber footbridge

Maderas: Ciencia y Tecnología, 2014
In Brazil, the study of pedestrian-induced vibration on footbridges has been undertaken since the early 1990s, for concrete and steel footbridges. However, there are no recorded studies of this kind for timber footbridges.

Prioritizing Constructing Projects of Municipalities Based on AHP and COPRAS-G: a Case Study About Footbridges in Iran

The Baltic Journal of Road and Bridge Engineering, 2012
Each municipality has a certain budget for constructing, maintaining and repairing every year. Prioritizing projects is one of the difficult issues of decision making and takes time for evaluating and programming.

Human‐Induced Vibration of Long‐Span Multi‐Layer Composite Beams—Analytical Calculation Method

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT The finite element method (FEM) provides a general framework for analyzing virtually all types of structures under various loading conditions. Nevertheless, in certain situations, designers may identify that the structural system exhibits predominantly beam‐like behavior, allowing the use of analytical theories.

WALKING-INDUCED VIBRATION OF A FOOTBRIDGE [PDF]

Proceedings of the 5th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2015
In the last years, the need for structures able to link the functional and aesthetic role has led engineers and architects to design footbridges characterized by long span, light materials and increasing slenderness. The low ratio between permanent and variable loads makes recent footbridges more sensitive to the dynamic loads, such as the forces ...

A common framework for the robust design of tuned mass damper techniques to mitigate pedestrian-induced vibrations in lively footbridges

, 2021
The dynamic response of modern slender footbridges is usually sensitive to both the pedestrian actions and the uncertainties associated with their inherent structural behavior.
