Influence of transient operation modes of equipment on the stress-strain state of structures

The article presents the results of the expected calculations of floor slabs for loads excited in operating and transient modes. Particular attention is paid to the issue of the influence of the time of starting and stopping the machine on the amplitude of vibrations of structures in transient conditions. The main purpose of the study is to determine the magnitude of the resonant increase in the oscillation amplitudes compared to oscillations in the operating mode, as well as to analyze the effect of the equipment start and stop time on the resonant amplitude.
