Discusses the current problems of calculations of reinforced concrete slabs. A full calculation of the reinforced concrete Foundation slab of a 17-storey residential building based on the finite element method using the estimated complex with the collection of loads in accordance with SP 20.13330.2011 "Loads and impacts". We study the dependence of the distribution of the zones of maximum precipitation of the plate from the shape of the building and the location of the loads. By results of calculations the analysis of obtained results and conclusions.

Keywords: the finite element method, the coefficients of the elastic Foundation, the maximum settlement of the building, SCAD 11.3, the coefficient of bed

Discusses actual problems of determination of the resistance and protection of concrete structures – slabs, produced by standart adopted in the Russian Federation and the United States. Studied national and international experience of evaluation and quality control, measures to preserve the integrity and stability of structures to various types of exposure. The focus is on those conclusions that must be made from the analysis of the causes of destruction in order to avoid future repetition of mistakes and miscalculations that are allowed currently in the design and construction of engineering structures and which often lead to the occurrence of accidents.

Keywords: methods of quality control, concrete structures, failures of engineering structures
