1. 1. Operational modal analysis and finite element modeling of a low-rise timber building

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Viktor Petersson; Andreas Svanberg; [2021]
   Keywords : Timber structure; Dynamic behavior; Operational modal analysis; FE-modeling; Mode shape; Natural frequency.; Träbyggnad; Dynamiskt beteende; Operational modal analysis; FE-modellering; Egenmod; Egenfrekvens.;

   Abstract : Timber is a building material that is becoming more common and of interest for use in high-rise buildings. One of the reasons is that timber requires less energy input for the manufacturing process of the material compared to non-wood based materials. READ MORE

3. 2. An Attempt Towards FE-Modelling of Fracture Propagation in Railway Wheels

   University essay from KTH/Spårfordon

   Author : Fred Öhnander; [2018]
   Keywords : Railway wheel; Wheel-rail contact; Wear; Fracture initiation; Physical fracture propagation model; FE-model; Fracture mechanics; XFEM; Inclusion; Järnvägshjul; Hjul-räl-kontakt; Slitage; Sprickinitiering; Fysisk sprickbildningsmodell; FE-modell; Frakturmekanik; XFEM; Imperfektion;

   Abstract : The demand for higher velocities and heavier axle loads for freight trains leads to higher forces on the railway wheels which in turn lead to an increase in stresses on and below the surface of the wheel-rail contact. By time, this induces wear on the wheels which consequently lead to higher maintenance costs and in some cases accidents. READ MORE

4. 3. Dynamic Soil-Structure Interaction of a Portal Frame Railway Bridge - Numerical Analysis on a Case Study Bridge

   University essay from KTH/Bro- och stålbyggnad

   Author : Rita Ikzer; [2018]
   Keywords : Dynamic Analysis; Soil-Structure Interaction; Damping; Railway Bridge; Portal Frame Bridge; Full FE-Modeling; Simplified Modeling; Dynamisk analys; Jord-struktur interaktion; Dämpning; Järnvägsbro; Plattrambro; Detaljerad FE-modellering; Förenklad modellering;

   Abstract : In the field of structural dynamics, a broader knowledge about relevant phenomena that affect the dynamic behavior of railway bridges is vital for structural engineers and design code administrators. The knowledge might benefit in an increased understanding of e.g. the resonance phenomena, and in improvements of the existing design codes. READ MORE

5. 4. Numerical Evaluation of Structural Behavior of the Simply Supported FRP-RC Beams

   University essay from KTH/Betongbyggnad

   Author : Marjan Shahrokh Esfahani; Rasoul Nilforoush Hamedani; [2012]
   Keywords : ;

   Abstract : The main problem of steel-reinforced concrete structures is corrosion of steel reinforcements which leads to premature failure of the concrete structures. This problem costs a lot annually to rehabilitate and repair these structures. READ MORE
