  1. 21. Cost optimization of composite bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Markus Lythell; Jonathan Stenberg; [2020]
    Keywords : Composite bridge; Optimization algorithm; Pattern search; Cost optimization; MATLAB; Samverkansbroar; Optimeringsalgoritmer; Pattern search; Kostnadsoptimering; MATLAB;

    Abstract : Today in most design offices the practice when designing infrastructure is to adopt a trial-and-error based approach. This means that one solution to the problem is evaluated and based on the results the design is altered. This process is then repeated until satisfactory results have been achieved. READ MORE

  3. 22. 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

  4. 23. A 3D sliding bearing finite element based on the Bouc-Wen model : Implementation in Abaqus

    University essay from KTH/Bro- och stålbyggnad

    Author : Rémi Lantoine; [2020]
    Keywords : Railway bridge; dynamics; resonance; sliding bridge bearings; finite element; Abaqus; friction; steel; Teflon; PTFE; Bouc-Wen model; friction coefficient; temperature; heating;

    Abstract : As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. READ MORE

  5. 24. Dynamic Soil-Structure Interactionof Soil-Steel Composite Bridges : A Frequency Domain Approach Using PML Elements and Model Updating

    University essay from KTH/Bro- och stålbyggnad

    Author : DIEGO FERNANDEZ BARRERO; [2019]
    Keywords : Dynamics; soil-steel bridges; soil-structure interaction; model updating; PML; particle swarm; corrugated steel plates; frequency domain assurance criteria; parallel computing 2;

    Abstract : This master thesis covers the dynamic soil structure interaction of soil-steel culverts applyinga methodology based on the frequency domain response. At the first stage of this masterthesis, field tests were performed on one bridge using controlled excitation. READ MORE

  6. 25. The Nordic Prediction Method For Railway Traffic Noise : Improvements of the current corrections forrailway bridges, switches and crossings

    University essay from KTH/Byggnadsmaterial

    Author : KRISTÍN HELGADÓTTIR; RAGNHEIÐUR BJÖRNSDÓTTIR; [2019]
    Keywords : The Nordic Prediction Method; Railway traffic; Railway noise; Noise measurements; Acoustics; Steel bridges; Concrete bridges; Switches; Railway crossings; Correction factor; Correction for track condition;

    Abstract : Railway noise is a very important and growing health hazard in today´s society.Railway systems pass through towns and cities and create noise. When trainsride through or over railway bridges, switches and crossings the noise increasessubstantially, causing great annoyance to the residents in the area. READ MORE
