As society advances and the rapid development of the construction market, China's building system from the original masonry structure-based structural system developed to the current structure of reinforced concrete and steel structures and other new structures, new technology and new material has been continuously developed and applied, the traditional system in the construction of a continuous is reform and innovation. From the development of the architecture system of Xianyang areas, the original multi-storey brick structure began to be gradually reinforced concrete structure to a high-rise building transition, reinforced concrete structure from the original structure in the form of a single framework for the development of the framework is now more common, frame-wall, shear wall structure, and other forms coexist, reinforced concrete structure height, materials, construction methods, etc. produced more or less the development and changes in the resistance of reinforced concrete structure will also change. The current resistance of reinforced concrete structures to investigate the statistical analysis of accurate evaluation of the current level of residential structural reliability of great theoretical and practical significance.In conjunction with our own work, the paper survey of Xianyang region in recent years the development process of building structure, the current resistance level and the existing problems. In Xi'an, Xianyang City and the surrounding counties targeted at the concrete structure of the past four years the 1000 structure construction material properties and geometry parameters of the site surveys, has achieved a number of performance and reinforced concrete strength and the various types of steel concrete structures on the main geometric parameters of the measured data. Further application of statistical methods to its probability of a statistical analysis is given of reinforced concrete strength and the performance and characteristics of the statistical component size parameters, and components of the material properties and geometrical parameters of the main influencing factors focus on analysis, reinforced concrete for the establishment of accurate the probability of structural members resistance model and statistical parameters laid the foundation. From the external environment and the relationship between the durability of concrete structures based statistical analysis of the present situation and environment in Xianyang development trend in recent years including the environmental temperature, relative humidity, corrosive gases in the atmosphere and the concentration of acid rain and other meteorological parameters and environmental quality parameters , and systematic analysis of the various factors on the durability of concrete structures mechanism and extent of the effect.Based on Xianyang region with the new structure of the resistance and the external environment survey analysis, the establishment of the regional structure durability of Xianyang consider ways of life in Xianyang in concrete carbonation level, and focused on the construction of structural concrete carbonation level on the impact of life. |
