  1. 1. Pavement Response to Moving Loads

    Författare :Parisa Khavassefat; Björn Birgisson; Denis Jelagin; Andrew Collop; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The response of flexible pavements at vehicle-road interaction has been studied in this thesis. A quasi-static and a dynamic framework for analysing the pavement structure under moving load has been developed. Both frameworks are general, robust and computationally efficient. LÄS MER

  3. 2. Response of cable-stayed and suspension bridges to moving vehicles : Analysis methods and practical modeling techniques

    Författare :Raid Karoumi; KTH; []
    Nyckelord :cable-stayed bridge; suspension bridge; Great Belt suspension bridge; bridge moving loads; traffic-induced vibrations bridge-vehicle interaction; dynamic analysis; cable element; finite element analysis; finite diffrence method; tuned mass damper; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents a state-of-the-art-review and twodifferent approaches for solving the moving load problem ofcable-stayed and suspension bridges. The first approach uses a simplified analysis method tostudy the dynamic response of simple cable-stayed bridgemodels. LÄS MER
