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. Evaluation of a testing method for shear stiffness properties for cross laminated timber

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

   Author : Calle Lind; [2022]
   Keywords : CLT; cross laminated timber; EN 16351; four-point bending; rolling shear modulus; FE-modelling; Technology and Engineering;

   Abstract : Cross laminated timber (CLT) is an engineered wood product that was first developed in the 1990s. Since then it has grown in popularity thanks to its many advantages such as: low environment impact, high degree of prefabrication and low weight. As the material is relatively new the standardization process is still in the early stages. READ MORE

4. 3. Magnetic Resonance Elastography in Muscle Tissue based on Anisotropic Assumption

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Frederick Holmer Fann; [2022]
   Keywords : Magnetic Resonance Elastography MRE ; Muscle Tissue; Anisotropic MRE reconstruction;

   Abstract : Mechanical properties of muscle tissue are linked to its function. Magnetic Resonance Elastography (MRE) has the capability toquantitively measure these mechanical properties of soft tissue in-vivo. However, most MRE methods assume tissue isotropy during MRE reconstruction which is not an appropriate assumption for muscle tissue. READ MORE

5. 4. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES

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

   Author : Emil Nilsson; [2021]
   Keywords : CLT; cross laminated timber; in-plane loading; out-of-plane loading; beam; rolling shear modulus; experimental tests; FE-modelling; Technology and Engineering;

   Abstract : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.

6. 5. Design of column bases concerning bending and shear nibs

   University essay from KTH/Byggteknik och design

   Author : Rodi Kay; [2021]
   Keywords : Column bases; Pelarfötter;

   Abstract : The purpose of the thesis is to find out how to design column bases with conventional methods presented by European standards and codes, but above all from the Steel Construction Institute's handbook on structural joints and compare it with finite element analyses. However, today there are no good instructions for how column bases exposed to multiaxial bending should be designed, where assumptions based on structural mechanics also was compared with computer tools.
