Pipe reinforcement pad calculation

Design of Isolated Square and Rectangular Footings (ACI 318-02) Notation: a = equivalent square column size in spread footing design = depth of the effective compression block in a concrete beam A g = gross area, equal to the total area ignoring any reinforcement A req = area required to satisfy allowable stress A s = area of steel reinforcement in

Area located at ring (reinforcing pad), A41 = (OD - ID) * Thickness T r * fr = (14 - 8.625) in. * 0.601 in. * (5700 psig / 8000 psig), where factor fr = S pipe / S pad (Where, reinforcing pad thickness (ring), T r = 0.687 (1-12.5%) = 0.687 (0.875) = 0.601 in.)
Bending up the steel reinforcement at the edges of the footing helps in resisting bond stresses. The diameter of the main steel reinforcement should not be less than 12 mm. To prevent cracking due to uneven settlement below the wall itself, additional reinforcement is used as shown in Fig.13-c and d.

In general a Reinforcing Pad for a standard piping "Stub-In" branch will be a ring shaped plate. The I.D. will be equal to the O.D. of the Branch pipe and the width of the Pad will be equal to one half the nominal diameter of the branch pipe.
