Abstract:
To avoid creating a moment at the anchorage, tendons are typically anchored at the centroid of the member. This results in a uniform compression in the member, which is added to the stresses from the bending of the member to complete the design. Anchoring the tendon at the member centroid leads to a challenge in the selection of the tendon profile for the end span of multi-span slabs and beams. The article provides a preferred tendon profile and example calculations.
