  1. 1. Variations in dynamic properties of a steel arch footbridge : An experimental study

    University essay from KTH/Bro- och stålbyggnad

    Author : Martin Földhazy; [2018]
    Keywords : Damping ratio; Natural frequencies; Temperature; static mass; Human structure interaction;

    Abstract : This study separately investigates how temperature as well as two real load-situations affects the modal damping ratio and natural frequencies of a 64.9m span steel arch footbridge. Measurements of acceleration have been completed which covers a temperature span of  to . READ MORE

  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. Hangarplatsen : gestaltningsidéer och teoretiska resonemang kring ett offentligt rum i Barkarbystaden norr om Stockholm

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Anders Isacson; [2017]
    Keywords : landskapsarkitektur; gestaltningsförslag; Barkarbystaden; Järfälla; hangar; omvandlad miljö;

    Abstract : När våra städer växer och nya stadsprojekt breder ut sig förändras landskapen. Platser omdefinieras genom att nya strukturer ersätter de gamla. Samtidigt är det inte ovanligt att spår efter tidigare markanvändning lämnas kvar när ett område ska omgestaltas. 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
