Vibration Serviceability of Footbridges Made of the Sustainable and Eco Structural Material: Glued-Laminated Wood [PDF]
Materials, 2022 In this paper, dynamic analyses of two untypical, modern footbridges made of glued-laminated timber are presented. One of them is among the longest cable-stayed bridges for pedestrians in the world, made of such a structural material. Both structures are

Prioritization of Resilience Initiatives for Climate-Related Disasters in the Metropolitan City of Venice. [PDF]
Risk Anal, 2022 Abstract Increases in the magnitude and frequency of climate and other disruptive factors are placing environmental, economic, and social stresses on coastal systems. This is further exacerbated by land use transformations, urbanization, over‐tourism, sociopolitical tensions, technological innovations, among others.

Modal identification and damping performance of a full‐scale GFRP‐SFRSCC hybrid footbridge
Structural Control and Health Monitoring, Volume 29, Issue 12, December 2022., 2022 Abstract Slender footbridges are prone to excessive vibrations due to pedestrian effects, and comfort criteria often govern their design. In this sense, composite materials that combine high damping capacity with relatively high stiffness and low mass can provide functional benefits.

Shock and Vibration, Volume 2018, Issue 1, 2018., 2018 This paper presents a numerical study on the deterministic and probabilistic serviceability assessment of footbridge vibrations due to a single walker crossing. The dynamic response of the footbridge is analyzed by means of modal analysis, considering only the first lateral and vertical modes.

Interaction between Walking Humans and Structures in Vertical Direction: A Literature Review
Shock and Vibration, Volume 2016, Issue 1, 2016., 2016 Realistic simulation of the dynamic effects of walking pedestrians on structures is still a considerable challenge. This is mainly due to the inter‐ and intrasubject variability of humans and their bodies and difficult‐to‐predict loading scenarios, including multipedestrian walking traffic and unknown human‐structure interaction (HSI) mechanisms.

Shock and Vibration, Volume 2014, Issue 1, 2014., 2014 Since 1995, we have been measuring the in situ dynamic characteristics of different types of footbridges built in Portugal (essentially steel and precast reinforced concrete decks) with single spans running from 11 to 110 m long, using expedite exciting and measuring techniques.

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.

Ambient Vibration Testing for Story Stiffness Estimation of a Heritage Timber Building
The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013 This paper investigates dynamic characteristics of a historic wooden structure by ambient vibration testing, presenting a novel estimation methodology of story stiffness for the purpose of vibration‐based structural health monitoring. As for the ambient vibration testing, measured structural responses are analyzed by two output‐only system ...
