  1. 1. 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.

  3. 2. 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

  4. 3. 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

  5. 4. Modal analysis of pedestrian-induced torsional vibrations based on validated FE models

    University essay from KTH/Bro- och stålbyggnad

    Author : Simon Chamoun; Marwan Trabulsi; [2017]
    Keywords : Modal analysis; validated FE models; pedestrian-induced vibrations;

    Abstract : Finite element (FE) models serve as the base of many different types of analysis as e.g. dynamic analysis. Hence, obtaining FE models that represent the actual behaviour of real structures with great accuracy is of great importance. READ MORE

  6. 5. Modelling Pedestrian-Induced Vertical Vibrations of Footbridges

    University essay from Umeå universitet/Institutionen för fysik

    Author : Emma Zäll; [2015]
    Keywords : Footbridge; Pedestrian-induced; Vertical vibrations; Pedestrian-footbridge interaction; Structural dynamics; Crowd simulations.;

    Abstract : A pedestrian crowd walking on a footbridge causes the footbridge to vibrate. These vibrations become an issue of serviceability and can give rise to discomfort for the pedestrians, whereby they should, to as large extent as possible, be prevented. READ MORE
