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

    Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Bro- och stålbyggnad

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

    Sammanfattning : 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.

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

    Master-uppsats, KTH/Bro- och stålbyggnad

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

    Sammanfattning : 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. LÄS MER

  3. 3. Modelling Pedestrian-Induced Vertical Vibrations of Footbridges

    Master-uppsats, Umeå universitet/Institutionen för fysik

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

    Sammanfattning : 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. LÄS MER

  4. 4. Computational model for morality and emotions in EmoBN

    Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Medie- och InformationsteknikLinköpings universitet/Tekniska högskolan

    Författare :Henry Fröcklin; [2014]
    Nyckelord :artificial; general; intelligence; moral; decision making; appraisal; emotions; expected; moral; bystander; footbridge; trolley problem; MFT; UMG; behaviour network; EmoBN; EEN;

    Sammanfattning : This master thesis presents an approach on how to design moral behaviour in a scenario with een. een is an iteration of emobn which is based on bn, an action selection system with activation dynamics among modules, goal oriented and capable of prediction and planing. LÄS MER
