  1. 1. Reduction of Vertical Acceleration in High-speed Railway Bridges Using Post-installed Viscous Dampers : A case study of the Bothnia Line

    University essay from KTH/Bro- och stålbyggnad

    Author : Sarah Rådeström; Viktor Tell; [2014]
    Keywords : Structural dynamics; viscous dampers; high-speed trains; resonance; bridge design; bridge construction; Strukturdynamik; viskösa dämpare; höghastighetståg; resonans; brokonstruktion;

    Abstract : Several of the bridges along the Bothnia railway line do not fulfill the requirements regarding vertical accelerations that are stated in current design codes. The acceleration of the bridges needs to be reduced, in order to make the Bothnia line suitable for high speed railway traffic. READ MORE

  3. 2. Influence of the Non-linear Effects in the Design of Viscous Dampers for Bridge Cables

    University essay from KTH/Byggvetenskap; KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Author : Yalda Acar; Pontus Jingstål; [2014]
    Keywords : Bridge cables; external viscous damper; half-power bandwidth method; loss factor; non-linear vibration; Brokabel; externa viskösa dämpare; half-power bandwidt metoden; förlustfaktor; icke-linjär vibrationer;

    Abstract : In this master thesis the performance of external viscous dampers attached to cables in cable-stayed bridges have been studied. A comparison has been performed between a linear and a non-linear cable model. The comparison was carried out for two bridge cables, one from the Dubrovnik Bridge and the other from the Normandie Bridge. READ MORE
