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. A parametric study of the static and dynamic performance of timber arch footbridges with different hanger configurations

   University essay from KTH/Bro- och stålbyggnad

   Author : ALEJANDRO GARCÍA GARCÍA; [2022]
   Keywords : Arch bridges; footbridge dynamics; critical load; bridge typology; parametric study;

   Abstract : The influence of the hanger configuration in the arch and deck bending moments under asymmetric loads is widely used nowadays for improved designs of arch bridges. In this work, by means of a parametric study, those hanger configurations that most efficiently increase both the natural frequencies and buckling factors are identified, simultaneously evaluating the dynamic and static performance of timber arch footbridges.

4. 3. Barriers and Bridges for Establishing Agroforestry : A qualitative study of Swedish land use policy in relation to agroforestry

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Linnéa Pasquier; [2020]
   Keywords : Agroforestry; policy; financial support; agriculture; forestry; political ecology; landscape value; Common Agricultural Policy; Rural Development Program; Sweden;

   Abstract : Numerous scholars describe agroforestry as an extraordinary food production system that generates viable ecosystems and accommodates regenerative capabilities. Agroforestry may therefore be a promising solution to the future environmental challenges facing food production. READ MORE

5. 4. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

   University essay from KTH/Bro- och stålbyggnad

   Author : Turgay Dagdelen; Shaho Ruhani; [2018]
   Keywords : Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

   Abstract : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

6. 5. Structural design and performance of tube mega frame in arch-shaped high-rise buildings

   University essay from KTH/Bro- och stålbyggnad

   Author : Matiss Sakne; [2017]
   Keywords : high-rise building; tubed mega frame; arch-shaped structure; finite element method; P-Delta;

   Abstract : A recent development and innovation in elevator technologies have sprawled interest in how these technologies would affect the forms and shapes of future high-rise buildings. The elevator that uses linear motors instead of ropes and can thus travel horizontally and on inclines is of particular interest. READ MORE
