The paper is concerned with an optimal design of high-strength reinforcing lamella made from glued laminated timber structure controlled by the lamella thickness and material. The stepping stone for the present analysis are the results of nondestructive bending tests of thirty beams with different types of reinforcing lamellas adopting two material variants. Six different thicknesses were examined. The FEM models are created such as to exactly represent the tested beams which allows for a reliable comparison of measured and simulated data, e.g. center point deflection. As a next step, new FEM models are created for one particular real beam made from glued laminated timber reinforced by high performance lamella. Both thickness and material of this lamella are modified in individual numerical simulations to estimate an optimal degree of reinforcement with respect to the maximum deflection allowable for a given loading.
