ANALYSIS OF THE STATE OF STRESS AND DEFORMATION OF GLAMINATED WOOD FRAMES REINFORCED WITH COMPOSITE TAPES

In the modern world, construction industry is successfully developing in various directions. Large-sized structures are replaced by analogues reduced cross-section with help of types reinforcement.
 Frames refer to flat spacer structures. Modern glued frames often solid. Cross-section (lattice) this class were used mainly from solid wood. Currently, they practically not due lack their industrial production.
 Frame consist rectilinear elements and allow presence rigid (frame) nodes. Rigid nodes three-hinged usually called eaves, because have be constructed exactly under eaves building. These units ensure joint operation crossbars racks, which reduces bending moments crossbar. addition, it easily proven that maximum moment cornice less than beams same spans. Their ratio equal height frame strut arrow rise ridge relative support joints. Accordingly, unlike beams, can cover larger spans.
 However, largest made wood, requires significant material consumption. Therefore, research field strengthening such reduce relevant.
 Composite materials currently one leaders most composite well resistant many chemical influences: alkalis, acids, chlorides, sulfates, nitrates, others. This allows them both agricultural construction, where there a direct impact external environment on structure reinforced materials, residential buildings without harm residents.
 After analyzing stress-strain state modeling LIRA CAD software complex broken-glued wood integrally crossbar connection rack through toothed spikes along bisector corner tapes comparing similar reinforcement, we conclude perfectly combined allowing increase load-bearing capacity while reducing cross-section.
