BEARING CAPACITY OF PRECOMPRESSED LOAD-BEARING ELEMENTS MADE OF HEAVY CONCRETE UNDER SINGLE DYNAMIC LOADS

At dynamic load of high intensity, but of short duration, developing as a result of shock, explosive and seismic effects, there is an increased tensile strength of concrete-dynamic strength. This phenomenon is explained by the energy-absorbing ability of concrete operating during a short period of loading with a dynamic load only elastically.

In this work, the effect of long-term compression of heavy cement concrete of class B-15 on its strength and deformations under single dynamic loads was investigated.
