Strength assessment of reinforced concrete slabs for punching

Abstract

Strength assessment of reinforced concrete slabs for punching

Shogenov O.M., Beppaev A.M

The article analyzes the calculation of the punching shear slab structures according to the recommendations of SNiP 2.03.01-84*concrete and reinforced Concrete structures. It is shown that the existing method of calculation gives overestimated the bearing capacity of floor slabs in bezrigelny frame systems. In order to establish the bearing capacity corresponding to the constructive decision is expected by calculation to determine the angle of the pyramid pushing.

Keywords: extrusion, dowel effect, bezrigelny frame, preopera area, bearing capacity, punching the pyramid, technological hole, slab, reliability, rebar, concrete
