Features
The thickness of most long-span flat slabs, two-way slabs without beams, is controlled by the shear strength of the concrete slab surrounding the supporting column. The shear resistance of these slabs can be increased by means of shear reinforcement. If the shear resistance is increased, slab thickness can be decreased resulting in less concrete materials and lower structure deadweight, reducing costs. But installing typical shear reinforcement, shear heads, and stirrup cages is difficult and costly. To take advantage of the reduced slab thickness and decreased cost that shear reinforcement could provide, a more efficient shear reinforcement has been developed.
