2. 11. Thin-walled steel studs in fire : analysis and design recommendations

   Author : Peter Karlström; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : Development of steel frame modular buildings is gaining increased popularity and support throughout Europe. Due to flexibility in construction and good long-term performance, lightweight steel frame structures are often preferred solutions, for instance in partitions and suspended ceilings as well as for load-bearing elements.

4. 12. Stainless steel box columns in fire : analysis and design recommendations

   Author : Björn Uppfeldt; Olivier Vassart; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : The use of stainless steel in buildings is small but increasing, mainly due to the low maintenance costs, favourable corrosion resistance and aesthetic appearance. It is well known that stainless steel also performs better than carbon steel at elevated temperatures. READ MORE

5. 13. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

   Author : Anders Kullingsjö; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

   Abstract : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. READ MORE

6. 14. RoPax Ship Collision – a Methodology for Survivability Analysis

   Author : Per Hogström; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-linear FEA; failure modelling; uncertainty analysis; Crashworthiness; sheet metal failure; ship collision; damage stability;

   Abstract : Throughout the world, ships are continuously being declared as total losses and 10 to 15% of these accidents are collisions between ships. The consequences of a collision are diverse and depend on the ship type, e.g. oil outflow in the case of damaged tankers or loss of stability in damaged passenger ships. READ MORE

7. 15. Eigenfrequency Analysis FE-Adaptivity and a Nonlinear Eigenproblem Algorithm

   Author : Patrik Hager; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear eigenvalue; finite element; adaptivity; superconvergent patch recovery; rational krylov;

   Abstract : Engineering often pose the problem of computing the frequencies with which a system oscillates and the corresponding displacement patterns the system forms, and in case damping is present then the rates of which the amplitudes of the displacement patterns decay are also required. It is necessary to compute these quantities within a prescribed accuracy and the effort required for the computations should be minimised. READ MORE
