1. 1. Analysis of Footbridge Comfort Vibrations

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Niklas Thuresson; Henrik Ruuth; [2023]
   Keywords : footbridges; dynamics; vibrations; accelerations; Sétra; comfort vibrations; natural frequencies; Technology and Engineering;

   Abstract : The aim of this master's thesis was to investigate and increase the knowledge of how different parameters affect the dynamic properties of steel beam bridges used for pedestrian traffic. Steel footbridges are commonly used due to their high strength and low weight. READ MORE

3. 2. Design of footbridges subjected to dynamic loading

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Pontus Brynk; [2022]
   Keywords : Dynamic design; footbridges; SETRA; pedestrian loading; Technology and Engineering;

   Abstract : Modern design of steel pedestrian bridges often results in relatively light constructions with low natural frequencies were there is a considerable risk of resonance to occur from loads due to pedestrians. To resolve the problem a common solution is to increase dimensions of load bearing elements, resulting in greatly oversized elements with increasing costs and have substantial environmental impact.

4. 3. 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

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : William Johansson; [2019]
   Keywords : ;

   Abstract : Skellefteå Kraft has had high CO emissions problems in a bubbling fluidized bed (BFB) boiler in Malå.Statistical emissions data from 2013 to 2019 shows plant average emissions of 1230 ppm. Thisexceeds the recommended 440 ppm (6 % O2) that Naturvårdsverket proposes (Naturvårdsverket,2005). READ MORE
