| Abstract [eng] |
Composite structures of wood (CLT) and concrete are increasingly relevant in today's construction, but the methods of calculation and methods of connecting elements to each other are not quite well known. The final master's project analyzes the composite construction of wood (CLT) and concrete. For connecting composite structures to each other, notches and methods of connecting wood screws are used. As a result of a review of the literature analysis, it was found that composite overlays are characterized by very good mutual strength capable of withstanding a higher load and increasing the bending rigidity if both elements are well connected. There are many options for connecting elements to each other, the main connection methods are using dowels, screws, notches, glue, steel plates and notches with dowels together. Analytical manual calculations were carried out according to Eurocode 5, Annex B, the gamma method presented. The effective bending stiffness, deflection, first natural frequency and normal stresses of the composite overlay plate were calculated. Analogous calculations were carried out using the engineering program of finite elements Dlubal RFEM 5.25. The calculation methods carried out in comparison with the calculations made by the selected laboratory study, it was found why the comparative calculations differ. Thesis is comprised of: 41 p. of text without appendixes, 35 pictures, 7 tables, 47 bibliographial entries. In addition, the appendixes are included. |
