The main provisions of the methods of calculation of reinforced concrete structures

the methods of calculation of reinforced concrete structures are analyzed, making it possible to comprehensively evaluate the work of structures at various stages of deformation and ensure their reliability during operation by calculation. Due to the continuous development of urban planning, construction of transport facilities of chemical, oil, gas and other industries in seismically active areas of the Republic of Uzbekistan, the probability of occurrence and impact on the structures of buildings and structures of accidental short-term dynamic (seismic) loads of an emergency nature increases. The main requirement for buildings and structures is to withstand repeated exposure to short-term dynamic load without collapse. The disadvantage of the methodology of designing bases based on limit states is that during its development, the apparatus of reliability theory in its probabilistic interpretation was not consistently used to the end. It is a consistent approach to assessing the level of reliability by the probabilistic method that will allow us to establish a quantitative relationship between the characteristics of the variability of soil properties, loads and the calculated level of reliability. The establishment of such a connection will allow, in turn, to more correctly substantiate particular methods for determining the calculated values of the physical and mechanical characteristics of soils and the values of loads. At the same time, if necessary, the quantitative values of the correction coefficients appearing in the existing normative document can be more strictly determined.
