Introduction Application possibilities, as well as advantages and disadvantages of FRP materials in the form of bars, lamellas or fabrics used for strengthening of the compressed elements are well known and have already been widely presented (e.g. [1]).
Transfer of the transverse deformation between strengthening elements and newly added materials (FRP fabric) have to be ensured by sufficient roughness of surface.
The influence of slenderness is solved only in general terms in the design approaches and insufficiently describes the behavior of element strengthened by FRP materials.
