Threaded Rod and Column Base

This is how I install load bearing load bearing fiberglass columns in  a  high wind zone.  The columns are 10inch diameter placed on a 12 inch diameter concrete filled sono tube placed four feet into the ground.   A 5/8 inch anchor bolt is set into the concrete and a 5/8 threaded  rod is coupled onto it.  The rod is extended to the top of the header bearing over the column and bolted with a 2 inch plate and washer.  This has the effect of stabilizing the column and of tying the entire structure to the ground in a heavy wind.  The rafters are attached to the header with hurricane ties.
