About this detail

A post-tensioned concrete slab supported by columns incorporates tendons that are 1/2-inch diameter with plastic sheaths, forming a smooth parabolic curve between control points with supports and chairs maintaining the required profile. Maximum tendon spacing must not exceed eight times the slab thickness or 42 inches on center. Where construction joints are required, they are located where the tendon profile is at mid-depth. Continuous top and bottom reinforcement is provided along with class B lap splices and added bottom bars centered in the span as specified on the structural plans.
