Experimental investigations are described which showed that dry friction very substantially affects the vibration of building constructions, changing not only the amplitudes of oscillations, but also resonance frequencies experimental data are given on the forces of dry friction of concrete on concrete and concrete on steel which are necessary to dynamically design industrial buildings and constructions a method is presented for the calculation of forced nonlinear vibrations where dry friction is taken into account and the calculations of numbers of constructions are given the results of the studies are compared with experimental data practical recommendations for the calculations are given the possibility is shown of broadening the range of utilization of precast reinforced concrete for structures subjected to vibratory loads.
