Abstract
The article describes the main problems of engineering reinforced wooden structures associated with the justification of their reliability. Tasks to study the operation of a wooden reinforced beam taking into account the nonlinear operation of wood have been set and solved. A girder structure reinforced in the compressed and tensile zones by plate elements was used as the object of the research. To achieve the aims, the authors carried out an experimental study using strain-gauge equipment, numerical simulation of the structure in the ANSYS PC and analytical calculations. Based on the results, conclusions about the effectiveness of steel plate reinforcement in wooden beams have been made. The results can be applied in the engineering, and the developed structure can be used as the elements of the frame structures and as floor beams.
