Parametric analysis of the reinforcement of glued laminated timber beams with composite bars containing basalt fiber

Abstract Due to the greater importance put on the environment in the construction industry, wood, being a natural building material, has become more popular. It is of particular importance in the case of making elements with high aesthetic value and resistant to chemical corrosion. Due to high strength and, at the same time low weight, composite materials, especially fibrous composites, are also increasingly used. Among the fibrous composites, basalt fiber materials that are of natural origin and are ecological deserve attention. Therefore, the possible benefits resulting from the combination of two ecological materials was considered. In Ansys 16.1, a numerical model was created for parametric tests, assuming various construction configurations. In the ANSYS program, beams made of glued laminated timber, reinforced with BFRP bars, were modeled in various configurations of beam height, bar length, and bar distance from the lower and upper edge of the cross-section. The best results were obtained for the highest-height reinforced beams.
