Abstract EN
This paper introduced a strengthening technique for flat plates using steel stiffeners.
In this paper, the effectiveness of steel stiffeners with different arrangements and numbers on the punching shear strength.
The strengthening steel plates were extended from column to the slab and acted as a column capital of an equivalent concrete column capital.
The study was divided into two parts, the first part was the experimental study involves the molding three reinforced concrete flat slab strengthening with different dimensions and numbers of steel stiffeners, with changed the dimensions of steel plates for specimens (SS1 (100×100mm), SS2 (200×200mm), and SS3 (300×300mm)) in addition to reference model without strengthening.
The load-capacity of the strengthened slwas increased by (39.84% , 57% , and 99.2% ) respectively over that of the control specimen with sl(SS1, SS2, and SS3).
The second part that numerical modeling through the ABAQUS finite element program was introduced.
Effect of the steel stiffeners' size and the effect of the column's shape (rectangular and circular) that's deal with steel stiffeners were studied experimentally and numerically.
A good agreement was obtained between the experimental and theoretical This paper introduced a strengthening technique for flat plates using steel stiffeners.
