Research currently underway at the University of Wyoming is focusing on lower net compressive stress (prestress) levels that are likely to be used in the design of prestressed masonry structures. The research includes the construction of eight 8 inch wide x 24 inch long x 6 feet tall concrete masonry walls using face shell mortar bedding.

I am currently looking at NBC 2010 Earthquake Load and Effects to design foundations for a concrete silo. I have read the Users Guide - 2010 Structural Commentaries (Part 4 of Division B) and it states that NBC subsection 4.1.8 apply only to the seismic design of new buildings and should not be used for special structures.

Prestressed concrete explained. Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during its fabrication, in a manner that strengthens it against tensile forces which will exist when in service.

Stave silos are silos assembled from small precast concrete units called staves, usually tongued and grooved, and held together by exterior adjustable steel hoops. Other special terms are defined in the Commentary. 1.3Scope This Standard covers the design and construction of concrete silos and stacking tubes for storing granular materials.
For prestressed concrete cylindrical structures such as nuclear containments, tanks and silos, the curvature effect of the tendons introduces radial tensile stresses in the concrete shell which are generally neglected in the design of such structures.
Post-Tensioned Concrete Silos Reported by ACI Committee 313 The committee report gives design and construction requirements for concrete silos covered in "Recommended Practice for Design and Construction of Reinforced Concrete Bins, Silos, and Bunkers for Storing Granular Materials (ACI 313-77) and Commentary"
