The vibration mitigation method based on crowd flow control is verified by comparing the numerical and experimental results of its damping performance. pedestrian characteristics are simulated with upgraded social force model to include effects obstacles commute in a blocking scenario. coupling system’s equation established loading mass-spring-damping (MSD) structure crowd-footbridge vertical i...

Nagisa Bridge, a single span footbridge, was recently completed in Aomori prefecture, Japan. The structure of this bridge is a hybrid structure of cable-stayed prestressed concrete bridge and steel suspension bridge. It is the first application as this structure type of bridge in the world. Concrete girders near pylons are supported by stay cables. Steel girders are supported by suspension cabl...

Experimental and numerical studies for the structural vibration serviceability assessment of a historic suspension footbridge adopting non-invasive surveys low-cost equipment are presented. Field have been carried out to determine geometric properties, ambient tests performed estimate dynamic response under action single crossing pedestrian has recorded. Based on field surveys, 3D Finite Elemen...

We present an integration of rational moral reasoning with emotional intelligence. The moral reasoning system alone could not simulate the different human reactions to the Trolley dilemma and the Footbridge dilemma. However, the combined system can simulate these human moral decision making processes. The introduction of affect in rational ethics is important when robots communicate with humans...

This paper describes the finite element modelling, dynamic testing and finite element model updating of a newly constructed, 35m span, cable-stayed footbridge. A numerical simulation, using an updated FE model, was conducted to evaluate the accelerations that would be induced by a walking pedestrian. The results from the simulation were compared to corresponding experimental measurements, and w...

This work validates the simplified theoretical, analytical and numerical models used in preliminary design stage of 516 Arouca footbridge over River Paiva (Portugal), world's longest suspension footbridge. The were to define configuration bridge under static loading eigenfrequencies excited dynamic loading. three-dimensional finite element model detailed is briefly described. paper also present...

Vibrations are an issue of increasing importance in current footbridge design practice. More sophisticated footbridges with spans and more effective construction materials result lightweight structures a high ratio live load to dead load. As this trend, many have become susceptible vibrations when subjected dynamic loads. The most common loads on footbridges, other than wind loading, pedestrian...
