Concrete Slab Design
Shear Design: OneWay Slab
Shear design for a slab is similar to shear design for wide members. Therefore the requirement for no shear design is ^{[1]}:
øV_{c} ≥ V_{u}
where:
V_{c} = The shear acting in the concrete
V_{u} = the allowable shear for the concrete slab. The allowable shear can be calculated here.
V_{u} = the allowable shear for the concrete slab. The allowable shear can be calculated here.
Similar to beams, the critical shear section will act a distance "d" away from the face of the support. d = The depth to the rebar
