The research work is devoted to the questions of the technological providing and setting of the norms of the exactness of geometrical parameters of multi-storey framework-monolithic building’s constructions.
The research of complex process of constructing of multi-storey framework-monolithic building showed that quality of constructions depends on the using casing systems. The most widespread systems are the casing systems of the DOKA and PERI firms, which are exploited by constructing firms in Ukraine.
The analysis of the exactness of erection of vertical constructions of multi-storey framework-monolithic building gave the following results: from the data of executive geodesic surveys more than 6000 columns were set and their rejections submit to a law of normal distribution. It is an index of statistical homogeneity and stability of a technological process of their erection. The using casting systems, the modern methods of the geodesic providing and high-fidelity geodesic devices allow to erect constructions with high exactness, which exceed the exactness of the assembling of combined reinforced concrete constructions. The analysis of the histograms of rejections of columns from a vertical axis showed that the exactness of geometrical parameters of multi-storey framework-monolithic building’s constructions did not depend on a mark, where works and their geodesic accompaniment were conducted.
The application of methods of the theory of chances and operating state standards gave the possibilit
