Bidakov A. Increasing the strength and stability of plywood thin-webbed beams by creating X-form plywood web

In the dissertation work the new construction of glued thin webbed X-form beam with plywood web without cross ribs was investigated and behavior results of curvilinear plywood webs of beam in time of tests was obtained. Analyzed nature of behavior curvilinear webs of three beams with different bending radius of plywood webs in the tests enabled developed suggestions engineering calculation of new type of timber beam construction. Experimental researched beams is example of constructions without cross ribs where the question of reinforcement web buckling solved for account of creation stability curvilinear forms of plywood beam elements. All this makes it high-tech and economically sound. Comparison of experimental dates was carried out with results from modern calculated-analytical complex.
