Experimental Study of Plates for Punching Under Dynamic Loading

Abstract

the issues of strength and deformability of reinforced concrete floors during punching remain insufficiently studied at present, despite the available publications in the technical literature. This article presents the results of experimental studies on punching of fragments of conjugation of flat reinforced concrete monolithic slabs with a column under dynamic loading. The purpose of these studies was to obtain experimental data on the stress-strain state of a fragment of a monolithic floor during dynamic punching with varying thickness and class of concrete, to reveal the failure patterns of experimental samples, and to obtain new experimental data. A setup for dynamic testing is described. Comparison of breaking load for specimens tested under dynamic loading with breaking load for specimens tested for static load is presented. The angles of inclination of the punching shear pyramid under static and dynamic loading are indicated.

“…The re-routing of utilities is a rather complicated job requiring design documents developed based on the results of all types of survey affecting the safety of the construction (renovation) and the operation of the subject traffic infrastructure facility [14][15][16][17][18][19][20].…”
