Experimental investigations of reinforced concrete columns in the edge connection zone with a reinforced concrete slab

Abstract

In this paper the results of the experimental investigations of edge column – slab connections are presented and commented on. The load transmission mechanism between high strength concrete columns and slab made of normal, five times lower strength concrete was considered. The variable parameter of presented study was the overhang of slab cantilever. The performed study showed important effect of slab cantilever on effective concrete strength of column in the connection zone.
