Many post-tensioned buildings and parking garages are constructed with unbonded single strand tendons. When the strands terminate near or pass through a structural wall (shear wall), constructability is affected. Congested reinforcement in structural walls, especially in buildings constructed in seismic regions, impedes the placement of anchors and associated reinforcement. In addition, placement of anchorage within walls may make it impossible to use climbing forms to construct walls in advance of floors.
