Description
Summary:	The methodology for calculating the rigidity of monolithic reinforced concrete structures with cavities, located in one direction, is presented. According to the results of theoretical (numerical) modeling using the theory of shells and the finite element method, the values of cylindrical rigidity of hollow floors were obtained, which are different in both directions and smaller compared to solid slabs. The decreasing coefficients of cylindrical rigidity c x , c y depending on the geometric parameters of the cavities were determined. Deflections of the hollow floor of significant dimensions, in the plan on which the experimental studies were carried out, were calculated, taking into account the c x , c y coefficients. The obtained theoretical values of the deflections give a satisfactory convergence with the experimental values.
