Abstract

The main mechanical joints of wood and concrete in wood-concrete structures are considered, and a type of connection is proposed by means of concrete dowels formed during concreting of a wooden element with a drilled hole. A methodology for conducting experimental studies and a special test bench for determining the strength and deformability of samples during shear has been developed, which makes it possible to simulate the operation of a wood-concrete element during bending. Samples of wood-concrete structures have been manufactured and tested. The destruction of the sample (complete displacement of concrete relative to wood) occurred according to a brittle pattern due to the cut of the concrete dowel along the contact line of wood and concrete. The analysis of the results showed that the strength of concrete and the geometric dimensions of the cross-section of concrete dowels have a significant effect on the strength of the considered type of joint. A method for calculating the strength of wood-concrete bendable elements during shear along the contact of wood and concrete, based on the positions of the deformation calculation model, is proposed. The conducted studies have led to the conclusion about the effectiveness of the mechanical connection of concrete and wood in the form of concrete dowels of circular cross-section and the need for additional experimental and theoretical studies in composite wood-concrete bendable elements.
