  1. 1. Response of Footbridges equipped with TLD : A numerical and experimental assessment

    University essay from KTH/Bro- och stålbyggnad

    Author : Silhady Tshitende Luboya; [2020]
    Keywords : Tuned liquid damper; tuned mass damper; dynamic analysis; dynamics evaluation; vibration; footbridge; human-induced vibrations; parametric study; serviceability; assessment.;

    Abstract : In recent years, an increase to design slender and aesthetically-pleasing structures have resulted in some structures having a low natural frequency. This is because the design calculation did not meet the requirement of serviceability performance. READ MORE

  3. 2. Dynamic Assessment of Footbridges : A designer's method to estimate running induced vibrations

    University essay from KTH/Bro- och stålbyggnad

    Author : Jones Södergren; Anton Barraza; [2018]
    Keywords : Footbridge Dynamics; Running; Load; Vibrations; Structural Dynamics; Human Structure Interaction; Dynamic Assessment; Acceleration;

    Abstract : Dynamic problems in footbridges, such as sensible vibrations caused by human induced loading, has on a number of occasions been observed. These vibrations are rarely an ultimate limit state problem, but can be perceived as unpleasant by the pedestrian. In design guidelines there are propositions for how to asses the dynamic problem.

  4. 3. Serviceability assessment of footbridges when subjected to vibrations induced by running pedestrians

    University essay from KTH/Bro- och stålbyggnad

    Author : Javier Garmendia Purroy; [2017]
    Keywords : Footbridge; Running; Jogging; Load; Vibrations; Structural; Dynamics; Pedestrian footbridge interaction; Serviceability; Assessment; Gångbro; Löpning; Last; Vibrationer; Strukturdynamik; Bruksgränstillstånd; Bedömning;

    Abstract : Vibration serviceability in the design of footbridges is gathering enormous prominence as comfort restrictions get enhanced. Comfort verifications are often becoming critical when considering human induced dynamic loading on lightweight structures, which are increasing in slenderness and flexibility. READ MORE

  5. 4. Dynamic Analysis of the Skyway Bridge : Assessment and Application of Design Guidelines

    University essay from KTH/Bro- och stålbyggnad

    Author : Eric Thufvesson; Daniel Andersson; [2017]
    Keywords : finite element analysis; finite element modelling; footbridge; human induced vibrations; natural frequencies; mode shapes; parametric study; pedestrian bridge;

    Abstract : In recent years the design of pedestrian bridges has become more slender. As a result the bridges has lower natural frequencies and are more prone to excessive vibrations when subjected to dynamic loads induced by pedestrians. READ MORE
