  1. 1. CFD Analyses for Wind Load AssessmentCFD Analyses for Wind Load Assessment : Wind-induced vibrations in the Bomarsunds Bridge hangers

    University essay from KTH/Bro- och stålbyggnad

    Author : Fatiha El Azrak; [2023]
    Keywords : ;

    Abstract : The trend in recent years of building longer and slender bridge components has introduced new challenges to ensure their stability and strength. This master thesis focuses on the effects of wind-induced vibrations in the context of long, slender arch bridge components, particularly the recently constructed Bomarsunds Bridge in Åland, Finland.

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

    University essay from KTH/Bro- och stålbyggnad

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

    Abstract : 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.

  4. 3. 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.

  5. 4. A pre-study of the dynamic behavior of a single diagonal timber arch bridge

    University essay from KTH/Byggnadsmaterial

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

    Abstract : 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. READ MORE

  6. 5. Numerical and experimental dynamic analyses of Hägernäs pedestrian bridge : Including seasonal effects

    University essay from KTH/Bro- och stålbyggnad
