Concrete cover for reinforcement should be in accordance with ACI Table 20.5.1.3.1. Concrete The concrete cover is measured to the outer edge of ties, stirrups, or spirals if transverse reinforcement encloses the main bars.
Concrete exposure | Member | Reinforcement | Specified cover, in. |
|---|---|---|---|
Cast against and permanently in contact with ground | All | All | 3 |
Exposed to weather or in contact with ground | All | #6 through #18 bars | 2 |
#5 bar and smaller | 1-1/2 | ||
Not exposed to weather or in contact with ground | Slabs, joints, and walls | #14 and #18 bars | 1-1/2 |
#11 bar and smaller | 3/4 | ||
Beams, colums, pedestals | Primary reinforcement, stirrups, ties, spirals and hoops | 1-1/2 |
Cover or specified concreteare is defined as the distance between the outermost surface of embedded reinforcement and the closest outer surface of the concrete.
Development lengths of concrete beam reinforcement should be in accordance with Development of Reinforcement per ACI 318-19 with ideCAD title. In this case, for deformed bars or deformed wires, ld is calculated in accordance with ACI Table 25.4.2.3. Other conditions are described in the same title.
Splices of deformed reinforcement should be in accordance with Splices per ACI 318-19 with ideCAD title.
Transverse reinforcement is provided such that Ktr, along with development and splice lenghts lengths of longitudinal bars with fy ≥ 80,000 psi. Minimum The minimum value of Ktr is 0.5db. (Development of Reinforcement per ACI 318-19 with ideCAD)
Minimum reinforcement spacing s is determined according to Minimum Spacing of Reinforcement per ACI 318-19 with ideCAD title.
