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. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anders Tolf; Markus Johannesson; [2022]
   Keywords : Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

   Abstract : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. READ MORE

4. 3. 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

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. Cross-comparison of Non-Linear Seismic Assessment Methods for Unreinforced Masonry Structures in Groningen

   University essay from KTH/Betongbyggnad

   Author : Viktor Peterson; Zihao Wang; [2020]
   Keywords : Non-linear time-history analysis; non-linear pushover analysis; N2- method; equivalent frame model; continuum model; numerical seismic assessment; unreinforced masonry buildings iv;

   Abstract : A large amount of low-rise unreinforced masonry structures (URM) can be foundin Groningen, the Netherlands. More and more induced earthquakes with shortduration have been detected in this region due to gas exploitation. READ MORE
