The Masters thesis investigates the strength of beams, which are constituted from two wooden lumbers, which are connected by corrugated steel mesh. It was determined, that the strength of the beam depends from the corrugated steel ribbon length and the dimensions of the wooden lumbers. Strength calculations are performed by using the finite element method. The results were, that the weakest place of the heterogeneous bent beam is at the place of beam fortification: the stress intensity at this place is stronger from 1.1 to 4.4 times than at the middle of the beam. Work consists out of: conclusion, two main chapters, conclusions and references. The relevancy and novelty of the paper is discussed and the work object is presented, goals and task are formed and the research methodology is provided in the conclusion of the paper and work. The first chapter provides general knowledge about heterogeneous beams and their efficiency. The main materials, which are used for production of heterogeneousbeams, are discussed. The second chapter widely describes the investigative model of the heterogeneous beam and results are graphically presented.The results are reviewed and conclusions are formulated at the end of the paper. Work extent – 48 pages, 44 pictures, 3 tables, 12 bibliographic sources. |
