And also increase of durability of wooden designs with the help high-modular materials on an example of central connections. Object of research is the establishment of decrease in weariness of metal with a crack "preserved" carbon fiber-reinforced plastics an overlay and acknowledgement of this phenomenon on models of metal beams. Increase in rigidity and durability of wooden central connections, including a hyperbolic cover. Research methods: - The general methods of empirical and theoretical research - experiment, modeling and the analysis; - Numerical methods of calculation; - Methods of mathematical modeling; - Methods of the theory of elasticity and the theory of destructions. Scientific novelty of the received results consists in a substantiation of the new approach on delay of growth of fatigue cracks in metal with use of overlays from high the module materials: - For the first time experimental researches of laboratory samples of metal with an artificial crack the covered overlay from carbon fiber-reinforced plastic are spent, and also the model of a compound beam with carbons fiber-reinforced plastics overlays in places of possible formations of cracks is tested at action of cyclic loading; - The method of mathematical modeling of increase firmness to cracks beams under the crane around a crack with carbon fiber-reinforced plastics an overlay is developed; - For the first time the rigid knot with use carbon fiber-reinforced plastic for national teams glue the board elements of rectangular section with level-by-level reinforcing is developed and tested; On the basis of static and dynamic tests, numerical calculation of metal beams Recommendations about calculation and designing of metal designs are developed "at cyclic loading with method use" preservation of cracks"".
