ANALYTICAL COMPUTATION OF THE PUNCHING STRENGTH OF REINFORCED CONCRETE
The author develops an analytical expression to compute the punching strength of reinforced concrete using results obtained by numerical simulation of the failure phenomenon. The simulation shows that punching strength can be calculated by integrating the vertical tensile stresses around the punching crack. Punching strength is also expresed in terms of the tensile strength of concrete, percentage of flexural reinforcement, slab thickness, and radius of punching crack initiation. The effects of reinforcement are considered in a unified approach by adding the vertical tensile resistance of each type of reinforcement. Punching strength calculated with the developed analytical expression allows prediction of the experimental punching loads of slabs with various sizes, concrete strengths, and percentages of reinforcement, reinforced with ring reinforcement, orthogonal reinforcing bars, stirrups, shearhead, and prestressing tendons.
