1. 1. 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

3. 2. 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.

4. 3. Behaviour of cross laminated timber elements with openings at out-of-plane loading conditions

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

   Author : Christopher Hast; Daniel Fatemi; [2020]
   Keywords : CLT; Cross laminated timber; Grillage model; Gamma method; Bernoulli-Euler beam theory; Timoshenko beam theory; Finite element method; FEM; Composite; Abaqus; Technology and Engineering; Science General;

   Abstract : The use of cross laminated timber (CLT) is expanding, its use is relatively new and universal design standards are lacking. One situation for which no universal design standard exists is that of a CLT plate element with an opening. A grillage method has been proposed as a convenient method to design such plate elements.

5. 4. Finite Element and Dynamic Stiffness Analysis of Concrete Beam-Plate Junctions

   University essay from KTH/MWL Marcus Wallenberg Laboratoriet

   Author : Patrik Andersson; [2016]
   Keywords : Train-induced; vibrations; building; Finite Element Method; FEM; Dynamic Stiffness;

   Abstract : Measurements and predictions of railway-induced vibrations are becoming a necessity in today’s society where land scarcity causes buildings to be put close to railway traffic. The short distances mean an increased risk of the indoor vibration and noise disturbances experienced by residents. READ MORE

6. 5. Modification of Aeroelastic Model for Vertical Axes Wind Turbines

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Damoon Rastegar; [2013]
   Keywords : vertical axis wind turbine VAWT ; finite element method FEM ; Timoshenko beam theory; structural damping; modal measurement.;

   Abstract : In wind turbines, flow pressure variations on the air-structure interface cause aerodynamic forces. Consequently the structure deforms and starts to move. The interaction between aerodynamic forces and structural deformations mainly concerns aeroelasticity. READ MORE
