Modelování napojení samosnosných maloformátových dřevěných panelů

Abstract

Wooden building has been an integral part of construction for an exceptionally long time. Nowadays, when there is bigger requirement for rapid construction and the ecological side of buildings, the emphasis is placed on new ways of solving these constructions. Small-format wooden panels represent an effective way to speed up the construction and make the process more efficient. However, their mechanical properties are not sufficiently mapped, and the creation of models can help with better understanding of behavior of these structures. The main goal of this thesis was creation of joint models of prefabricated small-format wooden panels. This thesis deals with the historical and current use of panel wood buildings. It also contains information about joint design and principles of numerical modeling of timber. This thesis also describes the research carried out at the VŠB – Faculty of civil engineering, during which experimental testing of panels and their partial connections was carried out. The analysis of data, obtained from experimental testing, was the first step for creation of the model. Another essential part was evaluation of data and analytical calculation. The last part was transfer of the acquired knowledge directly into the software in which the numerical models were created. There are models of partial joints, thanks to which an inverse analysis of material properties was performed, and a small-format wooden panel. Subsequently, the work compares the results obtained from the models and the testing itself, thanks to which material that corresponded as closely as possible to reality was created.
