Calculation of boundary values for the thickness of flat reinforced concrete floors based on the punching condition
Incoming article date: 17.04.2025The area where the floor is supported by a column is one of the most critical areas in buildings with a load-bearing system made of monolithic reinforced concrete. This is due to the high concentration of forces and, as a consequence, the densest reinforcement within the floor. When designing such structures, the problem of initially setting the thickness of the floor from the conditions of punching arises, without yet having a spatial calculation scheme that allows correctly determining the bending moments in the node working on punching. In the article, conditions are obtained for the necessary and sufficient thickness of floors with and without transverse reinforcement depending on the punching force F in the column.
