Dynamic model updating including pedestrian loading applied to an arched timber footbridge

open access: yes, 2019
This paper shows the experimental procedure and numerical methodology used for the dynamic characterization and serviceability assessment abilities (by simulation) applied to a timber pedestrian walkway. The footbridge is a 47 meters long and 3.9 meters wide structure consisting on single wooden arch (3.4 m sag), wooden deck, steel hangers and steel ...

A parametric study of the static and dynamic performance of timber arch footbridges with different hanger configurations

open access: yes, 2022
The influence of the hanger configuration in the arch and deck bending moments under asymmetric loads is widely used nowadays for improved designs of arch bridges. In this work, by means of a parametric study, those hanger configurations that most efficiently increase both the natural frequencies and buckling factors are identified, simultaneously ...
