NOVELTY - The foundation has an annular concrete base embedded in a support surface. Tower anchor bolts (51) are in spaced relationship arranged as a ring around a center part of the foundation and embedded in the concrete base. A continuous strand reinforcing hoop is spirally wound around the center part of the foundation, and extends from near a bottom part of the embedded concrete base upwardly above a top part of the concrete base. The continuous strand reinforcing hoop includes an inner continuous strand reinforcing hoop and an outer continuous strand reinforcing hoop.    USE - Large concrete support foundation for supporting dynamic tall, heavy and/or large structures such as towers and poles, used to support various devices. Uses include but are not limited to support wind turbines, power transmission lines, street lighting and signals, bridge supports, commercial signs, motorway signs and ski lifts.    ADVANTAGE - The foundation ensures that a post-tensioned continuous strand hoop reinforcement compresses concrete between vertical or horizontal steel reinforcing rebars or bolts so as to prevent concrete cracking phenomenon and reduce foundation deflection, distortion, cycling and fatigue while increasing rotational stiffness in anchor caps, spread foundations and foundation configurations, thus prolonging service life of the foundation. The foundation reduces hoop placement time consumption and effort required by reducing a number of wire tie, steel handling and manpower required for rebar hoops.    DETAILED DESCRIPTION - The continuous strand reinforcing hoop is a continuous steel strand or cable. INDEPENDENT CLAIMS are also included for the following:    (1) a covered continuous steel strand or cable    (2) a post-tensioned continuous strand hoop reinforcement for a concrete foundation    (3) a method for constructing a pile anchor foundation in-situ.    DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a P and H spread foundation with tower anchor bolts, pedestal inner corrugated metal pipe, pedestal outer corrugated metal pipe, base perimeter corrugated metal pipe, embedment ring, grout trough, top horizontal steel bolts, bottom horizontal steel bolts, leveling course and continuous strand reinforcing hoops with coiled strand hoop guides.
