punching shear

punching shear

1. The shear stress calculated by dividing the load on a column by the product of its perimeter and the thickness of the base or cap, or by the product of the perimeter taken at one-half the slab thickness away from the column and the thickness of the base or cap.
2. The failure of a base when a heavily loaded column punches a hole through it.
3. The punching of a hole through a base by a heavily loaded column as a result of failure of the base.

This paper analyses the compliance of the design codes calculation methods for punching shear resistance in reinforced concrete slabs STR 2.
It has been determined that almost in all cases the difference between the punching shear resistance results received experimentally and theoretically is statistically significant.

Most works [1-4] analyse the impact of the main parameters on the punching shear resistance in reinforced concrete column-to-slab connections under axial forces.
Some works [1] provide a comparison of design codes punching shear resistance calculation methods.
Punching shear of slabs under axial forces in column-to-slab connection occurs when a punching cone is formed.
Concrete punching shear strength dependence on approximation of cylindrical compressive strength also differs.
The main code parameters of calculating punching shear in slabs are provided in Oable 1.
Further we concisely present different punching shear calculation methods when axial forces are located centrally.
The resistance of punching shear force by ACI is as follows:
Due to the spread of the punching shear resistance data obtained through experiments, theoretically obtained values will always differ from the experimental results.
