1. 1. Modelling Alternative Load Paths in Platform-Framed CLT Buildings : A Finite Element Approach

   Författare :Johannes Albert Josef Huber; Mats Ekevad; Ulf Arne Girhammar; Sven Berg; Sigurdur Ormarsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber; robustness; finite element method; alternative load paths; disproportionate collapse; Träteknik; Wood Science and Engineering;

   Sammanfattning : Timber has become more popular as a construction material during recent years. Engineered wood products, such as glued laminated timber and cross-laminated timber, have enabled the construction of multi-storey buildings. Tall buildings with many occupants need to resist a disproportional collapse in case of unexpected exposures, e.g. LÄS MER

3. 2. Numerical simulation of tube hydroforming : adaptive loading paths

   Författare :Joakim Lundqvist; []

5. 4. Cycle paths’ degradation processes and surface condition assessment

   Författare :Martin Larsson; Sigurdur Erlingsson; Anna Niska; Inge Hoff; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction design; cycle paths; degradation; distress modes; maintenance; municipalities; survey; cycling comfort; road surface measurements; surface evenness; surface texture; Building Materials; Byggnadsmaterial;

   Sammanfattning : A shift in modal share from car driving to cycling has many benefits, both from individual- and societal perspectives, e.g., better health from an increase in physical activity, lower levels of pollution and congestion. However, there are also some potential problems with such a shift. LÄS MER

7. 5. On the Design of Functionally Integrated Aero-engine Structures: Modeling and Evaluation Methods for Architecture and Complexity

   Författare :Visakha Raja; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Product Architecture; Aero-engine Structures; Configurable Components; Load Paths; Design Product Complexity; Functionally Integrated Product Architecture; Product Development; Structural Complexity; Function–Means Modeling;

   Sammanfattning : The drive for airplanes with radically reduced fuel consumption and emissions motivates engine manufacturers to explore innovative engine designs. The novelty of such engines results in changed operating conditions, such as newly introduced constraints, increased loads or rearranged interfaces. LÄS MER
