| Title of the article | Analysis of the operation of cylindrical polymer composite dowels in wooden composite bending elements |
| Abstract. | In the modern world the issue of affordable construction of buildings and structures in remote settlements, especially in the northern regions, is acute. The solution to this problem can be the widespread introduction of prefabricated structures, for example, from wood. The design of a composite wooden beam with polymer composite dowels considered in this article potentially has a number of advantages compared to traditional wood solutions, as well as compared to materials such as steel, reinforced concrete. The purpose of the work is to analyze the shear behavior of pins in a wooden bending structure. The objectives of the study are to create a wooden two-tier composite beam from beams combined with polymer composite dowels and to conduct a series of sample tests, determine the values of vertical deformations of the composite beam and the mutual displacement of the ends of the beams with a different number of dowels, in addition, to compare the experimental data obtained with analytical calculations. Results: Based on the experimental model of a composite wooden beam, successful integration of a dowel system into the overall performance of the composite structure was demonstrated. Analytical dependencies were derived to examine the influence of the number of dowels on the overall flexure of the investigated wooden composite element. Conclusions: For the considered wooden composite beam, a linear relationship between vertical deformations and the number of dowels can be affirmed under loads not exceeding 50% of the load-bearing capacity. Polymer composite dowels are not uniformly engaged in shear, as evidenced by the obtained deformations and failure modes of the wooden composite beams. It can be noted that the most effective number of dowels is six, positioned at the edges of the bending element. |
