This Series 500 ridge skylight sits on a integral tubular steel perimeter frame designed to allow the skylight to move independently of the 3 buildings it's attached to.
Siesmic as well as hurricane loading were taken into account during the design/engineering stage and the entire skylight, perimeter subframe and all sits on teflon slide plates supported by 6 large embedments which were also a part of this scope.
The Atrium skylight has seen some real combat conditions. During the walk-through inspection a concrete block fell from 8 floors above, landing in the middle of one of the glass lights. Amazingly it did not come through the glass. At least 3 major CAT 5 hurricanes have hit it since with no damages. Nobody knows for sure what the top wind speed was during Hurricane Lenny, as it snapped off the airport anemometer next door at 225 MPH. No glass was lost even after a direct hit by a flying palm tree.
The glass used was 9/16" HS Lami.
