  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 static behaviour of a single diagonal timber arch bridge

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Lovisa Öhgren; Malin Åström; [2020]
    Nyckelord :timber; single diagonal arch bridge; arch bridge; buckling; RFEM; deformation; ultimate limit state; serviceability limit state;

    Sammanfattning : The aim of this thesis is to study and gain more insight about the static behaviour of the three hinged single diagonal timber arch bridge in different situations. The bridge was tested for static analyses for both Ultimate Limit State and Serviceability Limit State, to investigate its behaviour and if it is possible to be built at the selected location.

  4. 3. Numerical and experimental dynamic analyses of Hägernäs pedestrian bridge : Including seasonal effects

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :AIDA IBISEVIC; HASANHÜSEYIN UGUR; [2019]
    Nyckelord :Pedestrian Timber Arch Bridge; Seasonal Effect; Modal Analysis; Dynamic Analysis; Finite Element Method; Experiments vi;

    Sammanfattning : Wood as a construction material has in recent years increased, in particular concerningpedestrian bridges. By utilizing wood, the ecological footprint can be reduced,and the material can be designed to comply with the increasing aesthetic demandbridge designers are facing. LÄS MER

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

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :John Peter Hallak Neilson; [2019]
    Nyckelord :Structural dynamics; Timber structures; Seasonal effects; Asphalt; Footbridges; Arch bridges; Dynamic analysis;

    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. LÄS MER

  7. 5. Skanstullsbron Library

    Master-uppsats, KTH/Arkitektur

    Författare :Jialu Cai; [2019]
    Nyckelord : transformation ; library ; mega structure ; viaduct ;

    Sammanfattning : I describe library as a place where one can detach from everyday life and attach to things that happened hundreds of years ago, happen in the fantasy world, happen in the spiritual space. With this description I regard library as a spiritual space rather than a functional building. LÄS MER
