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...

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...

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...

The Pont del Petroli pier is a coastal structure located in the town of Badalona, north Barcelona, Spain. was built 60s to allow mooring petroleum tankers, but fallen disuse 1990. Restored between 2003 and 2009, now regarded as historical social asset Catalan coast. In January 2020 storm Gloria (Amores et al., 2020), characterized by extreme wave conditions (recorded offshore significant height...

To account for vertical human-structure interaction (HSI) in the vibration serviceability analysis, contact force between pedestrian and structure can be modelled as superposition of induced by on a rigid surface resulting from mechanical human body. For case large crowds, this approach leads to (time-variant) models with very high number degrees freedom (DOFs). simplify paper investigates perf...
