depends on where you are in CT. Local codes supersede national so check with your local building department. Thickness also varies. For instance nassau/suffolk counties in new york have been hurricane zones for several years now - our anchor bolts are 5/8". 6"-12" off corner and then spaced depending on locality. Depends on design wind load and height of building. Anywhere from two to four feet on center.
12" in from corner then 4' oc is standard. Then the engineers get involved. I did a 5 story condo in Ocean Shores, WA built to 130+ MPH wind loads. The anchor bolts were 5/8" at 10" oc for the entire north side wall. It was insane.
