Evaluating vibrations on a small-scale model of a timber footbridge [PDF]

open access: yesMaderas. Ciencia y Tecnología, 2014
In Brazil, the study of pedestrian-induced vibration on footbridges has been undertaken since the early 1990s, for concrete and steel footbridges. However, there are no recorded studies of this kind for timber footbridges. Brazilian code ABNT NBR 7190 (1997) gives design requirements only for static loads in the case of timber footbridges, without ...

Standards guidelines for human comfort tested on timber footbridges

open access: yesSemina: Ciências Exatas e Tecnológicas, 2011
Activities such as walking, running and jumping can produce undesirable dynamic excitations, which are a phenomenon that occurs due to pedestrian-induced dynamic forces whenever a footbridge features a natural frequency within stepping frequency ranges. Dynamic evaluations of timber footbridges are necessary to verify the level of human comfort and the

Temperature effects on the natural frequencies and modal dampings of timber footbridges with asphalt pavement

open access: yes, 2011
Timber bridges with decks made of laminated solid timber panels are usually protected against mechanical abrasion and humidity with a mastic asphalt pavement. Recent laboratory tests suggested that the pavement may have a significant effect on the stiffness and damping of a footbridge.

Vibrational performance of pedestrian bridges due to human-induced loads. [PDF]

open access: yes, 1997
The vibrational performance of footbridges due to human-induced loads has been investigated, based on modal and pedestrian tests carried out on three prototype footbridges.

TIMBER FOOTBRIDGES – VALORIZATION OF PARAMETRIC ANALYSIS IN OPTIMIZATION OF LAYOUT OF BEAM BRIDGES

open access: yesModern structures of metal and wood, 2022
Paper presents results of the analysis of possible design solutions of timber beam bridges considering all usual demands for their stability, safety and functionality when they are designed to serve pedestrian and cyclist traffic, and, if necessary, traffic of emergency and service vehicles as well.

Modeling spatially unrestricted pedestrian traffic on footbridges [PDF]

open access: yes, 2010
The research into modeling walking-induced dynamic loading and its effects on footbridge structures and people using them has been intensified in the past decade after some high profile vibration serviceability failures.

FRACTURE ANALYSIS OF CROSS LAMINATED TIMBER SHEAR-WALLS WITH OPENINGS [PDF]

open access: yes, 2023
Strength capacity and deformation contributions of Cross Laminated Timber shearwalls with no openings are primarily governed by the behaviour of the connections.

Quantification of dynamic excitation potential of pedestrian population crossing footbridges [PDF]

open access: yes, 2011
Due to their slenderness, many modern footbridges may vibrate significantly under pedestrian traffic. Consequently, the vibration serviceability of these structures under human-induced dynamic loading is becoming their governing design criterion.

Vibration serviceability of footbridges under human-induced excitation : a literature review [PDF]

open access: yes, 2004
Increasing strength of new structural materials and longer spans of new footbridges, accompanied with aesthetic requirements for greater slenderness, are resulting in more lively footbridge structures.
