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

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :ALEJANDRO GARCÍA GARCÍA; [2022]
    Nyckelord :Arch bridges; footbridge dynamics; critical load; bridge typology; parametric study;

    Sammanfattning : 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 evaluating the dynamic and static performance of timber arch footbridges.

  3. 2. A pre-study of the dynamic behavior of a single diagonal timber arch bridge

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Xiaoqi Wang; Shufan Ye; [2020]
    Nyckelord :: single diagonal arch bridge; timber bridge; footbridge; finite element analysis; resonance induced vibration; bridge dynamics; dimensional analysis;

    Sammanfattning : The aim of this Master’s thesis was to study the dynamic behaviour of a special type ofpedestrian timber bridge with a single diagonal arch - a design proposal made in a previousstudent project. The bridge is intended to be built as a gateway to the Alfred Nobel’s Björkbornin the municipality of Karlskoga. LÄS MER

  4. 3. Numerical and experimental dynamic analyses of the Vega Pedestrian bridge including seasonal effects

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :John Hallak Neilson; [2019]
    Nyckelord :;

    Sammanfattning : As timber structures become increasingly relevant and sought after – since they enable improvements in building time while reducing a structure’s life cycle impacts – streamlining their design can have meaningful economic and environmental implications.For timber footbridges, its design is frequently governed by serviceability criteria linked to excessive vibrations.
