minimum reinforcement-precast slabs
 
minimum reinforcement-precast slabs
can anyone help me in determining required minimum reinforcing in a precast slab. the slab in question is a cover for a pit. loads are not significant. minimum reinforcing governs the design. aci code doesn't address this issue specifically.
find a job or post a job opening
minimum ratio of reinforcement area to gross concrete area is often specified at 0.0020 for deformed bars; maximum bar spacing of 12" center to center; minimum bar size #4.
