Application of dynamic tests for technical diagnostics of buinding structures of staying head frames
Abstract: There is considered a possibility of using the results of dynamic tests for a technical diagnostics of building structures of staying head frames. There is given a technique of dynamic tests of the staying head frame structures. It was established that the results of the dynamic tests allow making the current control of structural system integrity. Spectrograms of forced displacements make it possible to reveal dangerous resonance phenomena in the system “a head frame-a hoist engine” Spectrograms of dynamic stresses in the elements of the main bearing structures are the information for estimating and forecasting the life time of building structures by the fatigue strength criteria.
Keywords: staying head frames, dynamic tests, technical diagnostics.
