a) To control the crack width, the stress f; in deformed reinforcement closest to the tension
face shall be calculated based on the factored moment.
b) To control the crack width, the stress f. in deformed reinforcement closest to the tension
face can be taken as (2/3)f, as a simplification.
c) ACI318-19 does NOT limit the maximum spacing of flexural reinforcement on the
tension side of a beam.
d) For nonprestressed beams requiring longitudinal skin reinforcement, the spacing of skin
reinforcement shall NOT exceed the spacing given in 24.3.2 of ACI318-19.
e) Per ACI318-19, immediate deflections of nonprestressed beams can be calculated based
on properties of uncracked sections if the maximum moment Ma of the beam is smaller
than 2/3 of the cracking moment Mer.
f) Compression reinforcement does NOT influence time-dependent deflections of beams.
g) The maximum deflection due to live loads permitted by ACI 318-19 for a floor NOT
supporting or attached to nonstructural elements likely to be damaged by large
deflections is l/480, where I is the span length of the floor.
h) A tension failure of a reinforced concrete section could be a compression-controlled
failure.
i) For a column reinforced with spirals at a balanced failure, the strength reduction factor
ø shall be taken as 0.75 per ACI318-19.
