1. 11. 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. 12. 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. 13. 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. 14. 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

6. 15. Dynamic Analysis of Long Span Footbridges

   University essay from KTH/Bro- och stålbyggnad

   Author : YINA FAN; FANGZHOU LIU; [2015]
   Keywords : footbridge; pedestrian-induced vibration; Sétra; Eurocode; vertical acceleration;

   Abstract : A footbridge in Slussen is planned to be built and will connect the area of Gamla Stan with Sodermalm. As an increasing number of footbridges with large span tend to become more flexible and light these days, the corresponding dynamic problems due to decreased stiffness and mass draw much more attention.
