16. Nonlinear analysis of reinforced concrete slab on partially softening ground : Ickelinjär analys av armerad betongplatta på delvis uppmjuknande grund
Master-uppsats, KTH/BetongbyggnadSammanfattning : Reinforced concrete slabs are a conventional type of foundation that is widely used in residential, commercial and industrial buildings. Most of the slab foundations are constructed directly on the ground without another structural medium in between and some of the slabs are therefore influenced by ground softening. LÄS MER
17. Crack propagation in concrete dams driven by internal water pressure
Master-uppsats, KTH/BetongbyggnadSammanfattning : Concrete structures are in general expected to be subjected to cracking during its service life. This is the reason why concrete is reinforced, where the reinforcement is only activated after cracks occur. However, cracks may be a concern in large concrete structures, such as dams, since it may result in reduced service life. LÄS MER
18. Form Finding of Grid Shells - a Parametric Approach using Dynamic Relaxation
Master-uppsats, KTH/MekanikSammanfattning : The rapid development of computational capacity in recent years has expanded the possibilities of digital modelling in architectural design. Parametric design has emerged from these possibilities with a capacity to generate complex geometries which call for advanced structural systems. LÄS MER
19. Newton’s Method for a Finite Element Approach to the Incompressible Navier-Stokes Equations
Kandidat-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistikSammanfattning : The cG(1)cG(1)-method is a finite element method for solving the incompressible Navier-Stokes equations, using a splitting scheme and fixed-point iteration to resolve the nonlinear term u · ∇u. In this thesis, Newton’s method has been implemented on a formulation of the cG(1)cG(1)-method without splitting, resulting in equal results for the velocity and pressure computation, but higher computation times and slower convergence.

20. Pullout test of rock bolts at the Lima Hydropower station : -Assessment of the test method
Master-uppsats, KTH/BetongbyggnadSammanfattning : During construction of dams, rock bolts are in general installed in the interface between concrete and rock as an extra safety measure against overturning failure. These bolts are however not allowed to be taken into consideration for the stability calculations of large dams. LÄS MER
