  1. 6. A pre-study of the static behaviour of a single diagonal timber arch bridge

    University essay from KTH/Byggnadsmaterial

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

    Abstract : 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.

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

    University essay from KTH/Bro- och stålbyggnad

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Bro- och stålbyggnad

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

    Abstract : 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. READ MORE

  5. 9. By whose rules, for whose needs? The power of elites, livelihood implications and potential for resistance in two Nepalese community forest user groups

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Constantin Harrer; [2017]
    Keywords : community forestry; power; recentralization; professionalization; elite capture; livelihoods; resistance; Nepal;

    Abstract : The Nepalese community forestry program entitles user groups to autonomously manage their forest within the confines of an officially approved operational plan. While widely considered a conservation success, recent discourses on elite capture, professionalization and recentralization question the program’s anticipated social outcomes. READ MORE

  6. 10. Feasibility Analysis of a Fiber Reinforced Polymer Bridge

    University essay from KTH/Bro- och stålbyggnad

    Author : Neil Murphy; [2013]
    Keywords : Fiber reinforced polymer; FRP; plastics; life cycle cost analysis; life cycle assessment; LUSAS; finite element analysis; Friedberg bridge.;

    Abstract : When implementing a bridge design proposal, it is common that several alternatives be considered, each with a different material of construction. Traditional building materials used for the construction of bridges have mainly been concrete, steel, timber or aluminium. READ MORE
