  1. 1. Drop-weight impact tests on reinforced concrete beams

    University essay from KTH/Betongbyggnad

    Author : John Abdalnour; Milad Saliba; [2023]
    Keywords : ;

    Abstract : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. READ MORE

  3. 2. Methodology for analysis of vibration isolating systems

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Jonas Olsson; [2023]
    Keywords : Vibration;

    Abstract : Vibration causes problems in many kinds of machinery including fighter aircraft. It can, for example, cause structural fatigue, malfunction in equipment and injuries to humans. The sources of vibration are engines, flow disturbance and separation of external loads, to mention some. READ MORE

  4. 3. Predicting eigenvalues and eigenmodes in non-rectangular rooms with machine learning techniques

    University essay from KTH/Teknisk akustik

    Author : Oscar Lundin; [2022]
    Keywords : Machine learning; Finite elements; Plane wave decomposition; ResNet; Room acoustics; Tensorflow; Keras; Eigenfrequency prediction; Maskininlärning; Finita elementmetoden; Planvåguppdelning decomposition; Rumsakustik; ResNet; Tensorflow; Keras; Prediktering av egenvärden; Egenfrekvenser; Egenmoder.;

    Abstract : Knowing the eigenfrequencies and eigenmodes is of great importance to interior design and a common acoustic engineering problem. Challenges in noise control makes knowing the lower eigenfrequencies particularly important. READ MORE

  5. 4. Dynamic Analysis of Double Tee Floors Subjected to Human Activity : A comparison between a standard- and a modified cross section

    University essay from KTH/Bro- och stålbyggnad

    Author : Bjondina Hoti; Fadi Simonides; [2022]
    Keywords : ;

    Abstract : Building with larger spans and more slender elements is more common today since the demand for open floor plans has increased. The consequence is that low frequency floors and vibration problems arise. Such floors tend to undergo large vibrations since their low eigenfrequency coincides with the frequency which human activities have. READ MORE

  6. 5. Computationally Efficient Methods in Topology Optimization

    University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Author : Vilmer Dahlberg; [2022]
    Keywords : Topology Optimization; Eigenfrequency; Eigenmode; Reduced Order Model; Sensitivity Analysis; Deflation; Technology and Engineering;

    Abstract : In topology optimization, iterative, gradient-based methods are used to find the material distribution of structures which maximizes some objective function, typically the structures' stiffness, or in some cases the fundamental frequency. Finite element analysis is used to compute the structural response in each iteration, leading to large systems of equations. READ MORE
