1. 1. 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.

3. 2. Global analysis of a tubed structural system for an inclined slender tall building

   University essay from KTH/Betongbyggnad

   Author : LYDIA FOTEINI MARANTOU; PAULINA CHOJNICKA; [2017]
   Keywords : inclined tall building; Tubed Mega Frame; truss system; diagrid; concrete; composite; P-delta;

   Abstract : Building engineering is called upon to keep up with the pace and challenges of modern design, which aims not only to build higher and greener, but also to fulfill the demands of the growing population and simple human curiosity. The main purpose of this study was to examine the global behavior of a slender and inclined (V-shaped) 300 m high rise building with different structural systems applied. READ MORE

4. 3. STRUCTURAL ANALYSIS OF TRUSS CONSTRUCTION FOR WIND TURBINE BLADES

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

   Author : Björn Weddig; [2016]
   Keywords : Wind turbine blade; FRP; Truss system; Instability; Buckling; Non-Linear; Eigenvalue problem; Frequency response analysis; Transient dynamic response; Technology and Engineering;

   Abstract : The usage of wind turbines during the latest years has grown substantially and are becoming an increasingly important source of renewable energy, as many countries are trying to reduce their reliance on fossil fuels. In order to increase the effect of the wind turbines the length of the blades has been increased, which has also led to an increase of the cross-section dimensions. READ MORE

5. 4. Structural design of high-rise buildings

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

   Author : Erik Hallebrand; Wilhelm Jakobsson; [2016]
   Keywords : High-rise buildings; resonance frequencies; accelerations; shear flow; displacements; critical buckling load; finite element.; Technology and Engineering;

   Abstract : High-rise buildings are exposed to both static and dynamic loads. Depending on the method used and how the structure is modelled in finite element software the results can vary. Some of the issues and modelling techniques, introduced below, are investigated in this Master’s thesis. READ MORE

6. 5. Topology Optimization as a Conceptual Tool for Designing New Airframes

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Torstensson Joakim; [2016]
   Keywords : Topology Optimization; Inertia Relief;

   Abstract : During the two last decades, topology optimization has grown to be an accepted and used method to produce conceptual designs. Topology optimization is traditionally carried out on a component level, but in this project, the possibility to apply it to airframe design on a full scale aeroplane model is evaluated. READ MORE
