1. Micro-Structure Modelling of Acoustics of Open Porous Material
Sammanfattning : Transportation is a large and growing part of the world’s energy consumption. This drives a need for reduced weight of rail vehicles, just as it does for road vehicles. In spite of weight reductions, the vehicle still has to provide the same level of acoustic comfort for the passengers. LÄS MER
2. Design and verification of discontinuity regions in reinforced concrete structures with the strut and tie method : Stress redistribution due to cracking and plastic deformation
Sammanfattning : .... LÄS MER
3. Computational Methods in Conceptual Structural Design
Sammanfattning : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. LÄS MER
4. Shape Optimization for Electromagnetic and Quasimagnetostatic Applications
Sammanfattning : This thesis uses a continuum formulation of sensitivity for shape optimization in two-dimensional microwave scattering and quasimagnetostatic problems. The continuum sensitivity is obtained by solving an appropriate adjoint problem. LÄS MER
5. Assessment of prestressed concrete bridges loaded in combined shear, torsion and bending : uncertaintiers in deterministic and statistic methods
Sammanfattning : The aim of the thesis is to investigate the load-carrying capacity of bridges according to different models for shear in combination with bending, torsion and prestressing. The following models are studied: Model with traditional summation of the contributions from concrete and steel accroding to the Swedish Code BBK 94 Strut model according to the European code EC2 Modified Compression Field Theory from Canada The models are applied to the Källösund Bridge on the road to the island Tjörn on the West coast of Sweden.
