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.

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.

A crowd-structure interaction model to analyze the lateral lock-in phenomenon on footbridges [PDF]
, 2018 In this paper a simplified biomechanical crowd-structure interaction model is proposed and validated in order to analyse the lateral lock-in phenomenon on real footbridges.

On the politics of movement: Borderscapes, choreopolicing and choreopolitics
Transactions of the Institute of British Geographers, Volume 50, Issue 4, December 2025.Short Abstract The paper introduces choreography as a novel tool of analysis for investigating how movement shapes and is shaped by the apparatus of territorial security. It examines how dance choreography can intervene in security imperatives and enact embodied transgression.

Vertical ground reaction forces on rigid and vibrating surfaces for vibration serviceability assessment of structures [PDF]
, 2018 Lightweight structures are sensitive to dynamic force generated by human walking and consequently can exhibit excessive vibration responses. The imparted forces, known as ground reaction forces (GRFs), are a key input in the vibration serviceability ...

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 14, Page 3594-3609, November 2025.ABSTRACT Reinforced concrete (RC) bridges are designed to remain safe and functional for their lifetime, during which the impacts of aging may result in performance degradation. Steel bar corrosion is one of the most common causes of structural performance degradation in RC structures subjected to earthquakes in seismic‐prone areas.

Numerical and experimental assessment of a typical brazilian footbridge
Revista IBRACON de Estruturas e Materiais, 2018 For the range of medium spans, around 30 to 40m, composite footbridges are getting popular in Brazil. This kind of structure consists on longitudinal steel truss beams providing support for a concrete deck usually made of precast elements.

Human-structure interaction effects on the maximum dynamic response based on an equivalent spectral model for pedestrian-induced loading [PDF]
, 2016 The paper investigates the effects of the human-structure interaction (HSI) on the dynamic response based on a spectral model for vertical pedestrian-induced forces.

Philosophy and Phenomenological Research, Volume 111, Issue 3, Page 753-772, November 2025.Abstract There is a metaphysical difference between person A killing person B and A merely letting B die. There is also a metaphysical difference between A saving B and A merely letting B live. This paper argues that the metaphysical difference between saving and letting live gives rise to a moral difference. It then puts that moral difference to work:
