Reinforced concrete flat slabs continue to be one of the most popular floor systems due to the speed of construction and their inherent flexibility in the layout of the premises. However, flat, non-rigid floors are subject to brittle fracture at the junction of the slab and column, which can spread and lead to the progressive collapse of a larger segment of the structural system. The lack of shear strength in two directions may be due to design errors, insufficient strength of the material, or overload.

This article discusses the results of studies of the behavior of reinforced concrete slabs during punching. The parameters affecting the shear strength of the joints of columns and slabs are considered. Studies of the influence of the strength of concrete, the location of reinforcement, the reinforcement coefficient, the shape and size of the column are given. Various types of reinforcement of reinforced concrete slabs in the punching zone are presented.
