1. 16. Safety formats for non-linear finite element analyses of reinforced concrete beams loaded to shear failure

   Master-uppsats, KTH/Betongbyggnad

   Författare :Anton Ekesiöö; Andreas Ekhamre; [2018]
   Nyckelord :nonlinear finite element analysis; estimation of coefficient of variation; par- tial factor; model uncertainty; deep beams; shear;

   Sammanfattning : There exists several different methods that can be used to implement a level of safety when performing non-linear finite element analysis of a structure. These methods are called safety formats and they estimate safety by different means and formulas which are partly discussed further in this thesis. LÄS MER

3. 17. Finite Element Analysis of the Dynamic Effect of Soil-Structure Interaction of Portal Frame Bridges - A Parametric Study

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Turgay Dagdelen; Shaho Ruhani; [2018]
   Nyckelord :Soil-Structure Interaction; Railway Bridge; Portal Frame Bridge; Dynamic Analysis; Parametric Study; Nonlinear Analysis; Jord-struktur interaktion; Järnvägsbro; Plattrambro; Dynamisk analys; Parametrisk studie; Icke-linjär analys;

   Sammanfattning : In Sweden, the railway sector currently faces the challenge of developing its first high-speed railway line, in response to the need to provide faster domestic and international transport alternatives. High-speed train passages on railway bridges can cause resonance in the bridge superstructure, which induce high accelerations that should not exceed the limits stipulated in the current design code.

4. 18. Nonlinear Finite Element Analysis of Shrinking Reinforced Concrete Slabs-on-ground

   Master-uppsats, KTH/Betongbyggnad

   Författare :Shruthi Prakash; [2018]
   Nyckelord :Slabs-on-ground; Gradient shrinkage; Statical indeterminate structure; Vertical deflection and Cracking;

   Sammanfattning : Concrete slabs-on-ground are commonly used in many types of industrial floors, warehouses, highways, parking lots and buildings. Cracks and deflection of slabs are undesired events caused by differential shrinkage, which limits the service life of the slabs. LÄS MER

5. 19. Experimental and numerical fluid-structure interaction analysis of a suspended rod subjected to forced vibrations

   Master-uppsats, KTH/Marina system

   Författare :David Ahlsén; [2018]
   Nyckelord :;

   Sammanfattning : This study is evaluating Solid-Acoustic Finite Element modelling as a method for calculating structural vibration response in water. When designing for example vehicles, it is important to avoid vibrational resonance in any part of the structure, as this causes additional noise and reduced lifespan. LÄS MER

7. 20. Distribution of stresses and displacements in skewed concrete slabs

   Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

   Författare :Eman Ismail; [2017]
   Nyckelord :Skew Slab; Finite Element Analysis; FEM; slab behavior;

   Sammanfattning : A 3D nonlinear finite element analysis was developed for simulating the behavior of skewed concrete slabs and to identify the response of the slab with different angles and element sizes. The purpose of this research is helping the engineering and construction industry to utilize the FEM study and results more in different structural applications. LÄS MER
