Global Vibration Comfort Evaluation of Footbridges Based on Computer Vision [PDF]
Sensors, 2022 The vibration comfort evaluation is a control standard other than strength and deflection, but the general comfort evaluation method only considers the response of the mid-span position and does not consider the difference in the vibration response of ...

Vibration Serviceability of Footbridges Made of the Sustainable and Eco Structural Material: Glued-Laminated Wood. [PDF]
Materials (Basel), 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

City of Skywalks: Exploring Hong Kong’s Public Space and Power of Discourse from Footbridges
Social Sciences, 2022 As a public space and building, the footbridge is not just a physical concrete building but also carries people’s life experiences and beliefs. In Hong Kong, however, footbridges are a joint product of the government and property developers to control ...

Parameter Calibration of a Social Force Model for the Crowd-Induced Vibrations of Footbridges
Frontiers in Built Environment, 2021 A reliable prediction of the human-induced vibrations of footbridges relies on an accurate representation of the pedestrian excitation for different loading scenario. Particularly, the modeling of crowd-induced dynamic loading is a critical issue for the
