  1. 1. End-Shield Bridges for High-Speed Railway Full scale dynamic testing and numerical simulations

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Hesham Elgazzar; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-speed railway; end-shield bridges; structural dynamics; soil structure interaction; full scale bridge testing; controlled forced excitation; hydraulic bridge exciter; frequency response function; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The increasing need for High-Speed Railway (HSR) to reduce the travelling time requires increasing research within this field. Bridges are main components of any railway network, including HSR networks, and the optimization of their design for this purpose would contribute to a faster and more cost effective development of the HSR network.

  2. 2. Strengthening of concrete structures with CFRP shear strengthening and full scale applications

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Anders Carolin; Luleå tekniska universitet.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Structures can be in need of strengtheing due to many reasons, which are presented in this thesis. A literature review gives the existing methods for enhancing a structures load bearing capacity. In this thesis focus will be set at external bonding with carbon fibre reinforced polymers. LÄS MER
