PRECAST CONCRETE MANHOLES

Using an allowable concrete stress of 45% of the minimum specified compressive strength of 4,000 psi, the allowable compressive stress would be 1,800 psi. Substituting this value for s yields the following: = 3.4 s H 1,800 = 3.4H then H = 530 feet The above example illustrates that precast concrete manhole
