Originální abstrakt

The paper is focused on the problems of composite CFRP-reinforced timber beams. CFRP reinforcement is represented by the lamella externally bonded on the tensile part of the beam for the strengthening the member to increase in the resistance from the viewpoint of both the ultimate and serviceability limit states. The paper presents selected results of the measurement of the stresses in CFRP reinforcement and in timber base, which can give the information on the level of the mutual interaction between both materials and on the rightness of the substitute cross-section approach mentioned above in the case of timber beams. Actual normal stresses obtained from the tests have been used for the evaluation of actual characteristics of the substitute cross-section, especially the second moment of the area.
