This paper proposes a method of restoration of wooden structures by impregnating polymer composition based on epoxy resin, locally weakened destruction. Objective - research and development of technology for site remediation of wooden structures with areas of locally de-graded wood. We analyzed the causes of the destruction of wooden building structures. The pa-per sets out the methodology and the engineering based on the example of a wooden beam, the destruction of locally weakened in the core zone. Engineering calculations were confirmed by numerical experiments carried out in the program complex "Lira 9.6".
Article is devoted to consideration of the questions connected with decrease in expenses by production and realization of the made production. Research is conducted on the example of the furniture enterprise of the Voronezh region by JSC Grafskoye. Any enterprise constantly uses these or those resources connected with material, labor and financial inputs. On the basis of the carried-out analysis, on the example of financial and economic activity of JSC Grafskoye, conclusions are drawn, reserves of decrease in expenses at production are revealed, and also recommendations when forecasting costs of production are allocated.
An algorithm of the reinforced binding elements calculation with allowance for the physical strain of concrete and reinforcement has been suggested. The three linear diagram of the concrete condition and the two linear of the tensile reinforcement that correspond to the recommended norms in Russia have been used. The task has been solved by the method of linear approximation. The finite difference method has been used at each approximation that allows to define the beam rigidity individually for each dot j =1,2 , dotted on the beam with some small spacing. A method of determining the deflection curve bending, the bending moment, the rigidity as well as the compression areas of the reinforcement suitable for any deformation of the concrete most tensile fabric from 0 to limiting value ε_b2 has been suggested. A solution for the continuous three-span beam has also been introduced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
