While the use of reinforcement with 80 or 100 ksi (550 to 690 MPa) yield strength enables a reduction in the amount of steel required, it may also result in greater slab deflections. However, the potential for increased deflection can be counteracted using high-strength concrete. This study compares designs with different strengths of reinforcing steel and concrete using slab prototype from an existing building.
