The principle of reinforcing and strengthening timber elements can be considered to be a specific application. In the area of reinforcement, factors related to anisotropic timber properties must be taken into consideration. The authors of this article focus on evaluating the increased load bearing capacity of timber elements using FRP materials. Various marginal conditions, which have an impact on the value of strengthening, have been assessed in the experiments. These conditions included the type of fabric, its thickness, and the type of timber material. (solid and glued laminated timber, glulam). Furthermore, the types and causes of individual failures of both beams and FRP materials were analysed. The elasticity and flexibility characteristics of materials strengthened by such methods were determined. The relationships achieved were compared with a numerical model using a finite element method in the ANSYS program. However, the resultant values are not the only important considerations to be included in any proposal concerning the strengthening of timber constructions. To provide optimum behaviour of the strengthened construction it is also important to achieve an effective cooperation between fabric and timber surface. The experiment also involved an analysis of the influence of moisture content of the timber during fabric application.
