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

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

   Sammanfattning : 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.

3. 12. Improving incident reports in the swedish armed forces

   Författare :Ulrica Pettersson; Försvarshögskolan; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Incident reports; lessons learned; design science; memory psychology; cued recall; eyewitness testimony; Ledningsvetenskap; Ledningsvetenskap; Incident reports; lessons learned; design science; memory psychology; cued recall; eyewitness testimony;

   Sammanfattning : It is generally maintained that learning should be a part of the daily routines of many organizations; this is often referred to as lesson learned processes. The purpose of organizational learning is to foster improvements that seek to both reduce incidents and accidents and reduce their consequences when they nevertheless happen. LÄS MER

4. 13. Development and application of corotational finite elements for the analysis of steel structures in fire

   Författare :Luca Possidente; Jean-Marc Battini; Nicola Tondini; Paulo Vila Real; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermomechanical finite element; Shell element; 3D beam element; Steel structures; Buckling; Fire Safety Engineering; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Sammanfattning : The ignition and the propagation of a fire inside a building may lead to global or local structural collapse, especially in steel framed structures. Indeed, steel structures are particularly vulnerable to thermal attack because of a high value of steel conductivity and of the small thickness that characterise the cross-sections. LÄS MER

5. 14. Fire Dynamics in Multi-Room Compartment Fires

   Författare :Nils Johansson; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire safety engineering; fire dynamics; multi-room compartment; numerical experiment; small-scale experiment; hot-gas-layer temperature; hot-gas-layer interface height; reproducibility;

   Sammanfattning : Fire dynamics in multi-room compartments are explored in this thesis and new methods to study conditions in rooms adjacent to the room of fire origin are presented. Simple and transparent engineering methods can create good possibilities for understanding different complex phenomena present in fire science. LÄS MER

7. 15. Multi-Functional Composite Design Concepts for Rail Vehicle Car Bodies

   Författare :David Wennberg; Sebastian Stichel; Per Wennhage; Thilo Bein; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Car body; Composite; Finite element; Lightweight; Multi-discipline; Multi-functional; Optimisation; Rail Vehicles; Sandwich Panels;

   Sammanfattning : Structures and material combinations, tailored for multiple purposes, are within the reach of vehicle manufacturers. Besides reducing the environmental impact of the transportation sector these multi-functional structures can reduce costs, such as development, manufacturing and maintenance, and at the same time offer improved comfort to the passengers.
