| Abstract [eng] |
The aim of the Master's thesis is to determine the change of the physical mechanical properties of laminated veneer lumber (LVL) and glued wood (GLT) by changing environmental conditions and to use the obtained results in beam simulation. The work consists of three main parts: literature analysis, standard and non-standard research methodology, analysis of research results. The first part presents the structure of wood, mechanical and physical properties of wood, static and dynamic research methods, LVL and glued timber production lines. The second part identifies and describes standard and non-standard test methods. It also provides basic formulas that are used during the analysis. The third part presents the research results and analysis. The beam analysis of the finite element program also performs the received data. By summarizing master‘s thesis 6 main conclusions are given. Thesis consists of 63 pages of text, 58 figures, 8 tables and 50 references. |
