In the Erection section, the statement "It should be understood that anchor rods cannot be pretensioned ——" is not correct. It is possible, and in some cases advantageous, to pretension anchor rods. For pretensioning, it is necessary to use a washer, larger plate or other shape (i.e angle) at the embedded end nut or bolt head. Relying on bond to resist uplift of any kind is never acceptable.
