1. 21. Acoustic performance of timber volume elements

   University essay from Lunds universitet/Teknisk akustik

   Author : Oliver Olsson; [2020]
   Keywords : Impact sound insulation; Air-borne sound insulation; Cross laminated timber; CLT; Timber Volume Element; Vibration Insulation.; Technology and Engineering;

   Abstract : The thesis investigates the acoustic performance of light weight timber constructions known as timber volume elements and vibration insulation methods employed in these. Common materials used in light weight timber floor constructions and different floor configurations consisting of these materials were also studied. READ MORE

3. 22. FEM modelling of sound reduction index in partition CLT wall

   University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Teknisk akustik

   Author : Adam Hultin; Erik Hörström; [2020]
   Keywords : Technology and Engineering;

   Abstract : Constructing buildings with wood brings many advantages, especially regarding environmental aspects, which has brought an up-rise in these types of structures. However, one of the main issues regarding wooden structures is its tendency to perform poorly acoustically in lower frequencies compared to heavier structures. READ MORE

4. 23. Alternative Fire Protection for CL - Timber : A Pilot Study

   University essay from KTH/Byggteknik och design

   Author : Peter Taraldsson; Ted Sunesson; [2020]
   Keywords : Alternative Fire Protection for CL - Timber; Alternativa brandskydd för KL - träelement;

   Abstract : This essay is a feasibility study on alternative fire protection materials for CLT elements. The purpose isto investigate and compile reasonable alternatives to gypsum board and mineral wool which theproject can then continue to work on and to test and evaluate its fire engineering properties.

5. 24. 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.
