From individual behaviour to an evaluation of the collective evolution of crowds along footbridges

open access: yes, 2016
This paper proposes a crowd dynamic macroscopic model grounded on microscopic phenomenological observations which are upscaled by means of a formal mathematical procedure.

Experimental Assessment of Double‐Skin Tubular Columns Under Eccentric Loads

open access: yesce/papers, Volume 8, Issue 6, Page 455-460, December 2025.
Abstract The CFDST (concrete‐filled double‐skin tubular) columns consist of concentric steel tubes with concrete filling between them and have a lower self‐weight compared to other configurations of composite columns. Double‐skin columns provide good structural performance, even when subjected to seismic activity, explosions, and dynamic loads ...

Map++: A Crowd-sensing System for Automatic Map Semantics Identification

open access: yes, 2015
Digital maps have become a part of our daily life with a number of commercial and free map services. These services have still a huge potential for enhancement with rich semantic information to support a large class of mapping applications. In this paper,

Numerical modelling of vandalistic action on footbridge for pedestrians and bicycles

open access: yesBudownictwo i Architektura, 2011
The paper deals with numerical modelling of dynamic load acting on a footbridge. Two cases of loads caused by passing people have been considered: the load caused by crowd of people and by random stream of people.

Optimization of Shell Structures with Fuzzy Probability‐Based Random Fields Using Artificial Neural Networks

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.
ABSTRACT The structural design optimization aims for robust structures with minimal use of material resources, leading to slender and thin‐walled structures, which entail a higher risk of stability problems. This issue is further influenced by geometrical imperfections, which are subjected to uncertainties.

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

On the politics of movement: Borderscapes, choreopolicing and choreopolitics

open access: yesTransactions 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.
