A contractor wants to stop a cast-in-place floor beam pour away from a column line. For beams and slabs, where does ACI direct ordinary floor-system construction joints unless the design permits otherwise?
Correct Answer
B) Within the middle third of the span
ACI 318 provisions for construction joints in floor systems place ordinary joints within the middle third of spans unless the design documents or engineer approve another location. Other choices: the support face, a casual quarter point, or a reinforcing splice location does not match the ACI floor-joint placement rule.
