Construction was recently completed on the Apple Park Visitor Center

in Cupertino, California. The building is an impressive architectural

and structural statement dominated by a large column free space with

a significantly cantilevered and tapered roof system. The building is

enclosed by a twenty foot tall perimeter glazing system and covered

by a thin curved carbon fiber roof deck, resulting in an extremely

transparent building. To achieve such a large column free space with

dramatic cantilevers, while minimizing deflections in the glazing and

carbon fiber roof systems, the building utilizes a novel post-

tensioned steel roof structure that cantilevers nearly fifty feet from

the core of the building.
