Forecast of life large residential buildings in series 1-480 reinforcement corrosion relations

Abstract. Relevance. Annotation. Relevance. The problem of ensuring the durability of structures and buildings of concrete and reinforced concrete are now becoming increasingly important. Large scale use of these building materials under aggressive conditions cause substantial costs of funds for repairs and renewals during the lifetime of structures. The problem of ensuringthe durability of the structures of building the first mass series, revealing the features of stress-strain state (SSS) of large buildings in the corrosion relations, development and evaluation of methods to strengthen the technical and economic performance of large houses amplification methods is an actualscientific and practical problems. The purposeof this paper is to forecast the longevity of large apartment buildings in the 1-480 series ofcorrosion of reinforcement connections. Results. Built according to the kinetics of corrosion of reinforcing ties together with data on SSS bonds and especially their elimination and redistribution efforts that allow the space to plan the installation of the gain by a predetermined residual life. Scientific noveltyand practical significance. The estimates and forecast the longevity of large apartment buildings, taking into account the kinetics of corrosion of concrete and reinforcing relationships. Based on studies developed a process and method of calculation of the gainelements of large joints of the wall panels of residential buildings to ensure their longevity for a predetermined period of service.
