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 ...

Dealing With the Failure Risk in Modal Tracking and Condition Evaluation From Damage of Sensors in Long‐Term Monitoring Using Adaptive Strategy

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Modal tracking and condition evaluation are two important procedures in modal parameters based bridge condition evaluation, yet they always face the risk of failure due to the spatial aliasing caused by the damage of the sensors and the variation from the noise corruption.

Sparsity‐Constrained Online Identification of Parameter Degradation in Multidamper Systems

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
The long‐term degradation of damper performance under adverse conditions compromises energy dissipation, posing a potential risk to structural safety. Online degradation identification approaches provide benefits, including in situ evaluation, real‐time processing, and high computational efficiency, among which Kalman filter–based methods offer ...

Automated Operational Modal Analysis of Bridge Structure Based on Infinite Dirichlet Process Mixture Model Without Prior Threshold

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
As one of the vital steps for structural health monitoring, automated operational modal analysis (AOMA) without manual intervention remains one of the challenging problems because it requires processing large datasets and involves many user‐defined thresholds.

A 6 Metre Long Glass Footbridge for the Ancient Public Slaughterhouse of Pisa

Challenging Glass Conference Proceedings, 2016
This paper illustrates the design process and the load testing of a steel-reinforced laminated glass beam built for a 6 m span glass footbridge. This specific glass footbridge has been designed and tested to join two existing floors of the main room of a

Assessment of the dynamic structural behaviour of footbridges based on experimental monitoring and numerical analysis

Revista IBRACON de Estruturas e Materiais, 2020
This research work aims to investigate the dynamic structural behaviour and assess the human comfort of footbridges, when subjected to pedestrian walking, based on experimental tests and tuning of finite element model.

Building Weight Measurement by Human Shaker

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
The weight of a building is a fundamental parameter that plays a critical role in structural hazard assessment, finite element model updating, foundation settlement prediction, and other related fields. At present, two primary approaches are commonly used to estimate building weight: calculation based on design drawings and estimation from the total ...

Experimental Assessment of Double‐Skin Tubular Columns Under Eccentric Loads

ce/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 ...

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

Proceedings 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.
