Abstract

A precast concrete post-tensioned segmented equipment tower including a lower segment of a relatively larger diameter, an upper segment of a relatively smaller diameter, and a transition segment there between, with a post-tensioning tendon spanning these segments and imparting a compressive pre-load between the segments, and a slot formed in an inwardly protruding surface of the transition segment for receiving and laterally retaining the tendon during installation and tensioning. The slot may be defined in a saddle formed of high density polyurethane which is cast into the inwardly protruding surface. An intrados surface of the saddle may be curved to impart a bend in the tendon.
