Ivanitskyy A. Bending design of artificial elements in a closed cage.

TThe thesis is devoted to the research and development of methods of calculation elements of artificial stone materials (bricks, light concrete blocks and blocks of heavy concrete) in a locked cage flexible considering prestressing, holder of friction clutch, nonlinear material properties.The methods of calculation of structures in a closed cage flexible, taking into account pre-tension clips, clips about friction clutch, nonlinear material properties. Developed engineering methods of calculating the strength and deformability of bending elements with a flexible synthetic materials in a closed cage and method for determining the prestressing force with regard to friction clips. The method of calculation of such structures in the supercritical phase.Experimental research strength and deformability brick beams with steel band with clip, aerated concrete beams with steel wire clip with ribbon and polypropylene. Keywords: beams, bending elements, stone, concrete, flexible mount, the stress-strain state, strength, deformability.
