In the present study, the effect of using reinforced concrete column capital on the punching shear strength of flat slab was investigated. The study was divided into two lines, the first line was the experimental study involves the molding four reinforced concrete flat slab models with dimensions (1600×1600×100 mm) with three different dimensions of column capital (400×400 mm, 600×600 mm, and 800×800 mm) in addition to reference model without columns capital (column dimension 200×200 mm). The second line that numerical modeling through the ABAQUS finite element program was introduced. Effect of column’s capital size and shape of column’s capital (rectangular and circular) were studied experimentally and numerically. A good agreement was obtained between the experimental and theoretical study. The main conclusion that the punching shear strength of reinforced concrete flat slab was affected on the size and shape of a column capital.
