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
