2. 1. Resistance of polygonal cross-sections : application on steel towers for wind turbines

   Author : Olga Garzon; Carlos Alberto da Silva Rebelo; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : Wind power is considered an efficient alternative for production of electrical energy. One advantage that wind power offers compared to conventional ways of producing energy such as fossil energy and nuclear energy is the low emission of carbon dioxide “CO2” during production of electrical energy.

4. 2. Resistance of cold-formed high strength steel sections : Effect of cold-formed angle

   Author : Anh Tuan Tran; Lars Bernspång; Ove Lagerqvist; Torsten Höglund; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

   Abstract : Cold-formed steel members are increasingly used in industrial and civil construction. Their use allows optimised member cross sections and shapes, thereby reducing the amount of steel used as well as the weight of the structures and, consequently, reducing harmful effects on the environment.

5. 3. Fatigue assessment of complex welded steel structures

   Author : Johan Martinsson; Jack Samuelsson; Wolfgang Fricke; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Abstract : To improve the usage of material in fatigue loaded complex welded structures a better calculation method (based on FEA) is needed than what is available on the market and an improved management of weld quality. Improved FE-procedures are directly applicable to design of generic structural components within virtually all industries using CAD and FEtools, irrespective of industrial sector. READ MORE

6. 4. Strengthening reinforced concrete structures with FRP composites

   Author : Jincheng Yang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GFRP; finite element analysis.; corrosion; interfacial stress; externally bonded reinforcement; self-anchorage; CFRP; debonding; concrete structures; Fibre reinforced polymer; prestressing level;

   Abstract : Civil infrastructures made of reinforced concrete (RC) play an important role in the economic activities and services of society. However, signs of deterioration and functional deficiency are commonly found in existing RC structures. Thus, there is a great demand for upgrading the capacity and performance of existing concrete structures. READ MORE

7. 5. Innovative Construction of Student Residences : Frameup Project

   Author : Pedro António Pimenta de Andrade; Anders Sjelvgren; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : In the majority of university cities in Sweden, a strong demand for student accommodations has initiated various development and research projects focusing on costs reduction and fast execution. The present thesis brings up a solution based on the development of a feasible assembly concept and process, for a Modular Building erection, where prefabricated 3D Modules are assembled into a sway steel frame.
