About San Diego Public Library Dome

The San Diego Public Library Dome is comprised of steel sails with thousands of steel connection points to support the aluminum panel covering, which is perforated with thousands of light points allowing light to illuminate the space below. Triangular Vierendeel trusses outline each of the steel sails, which connect to form an arch, with additional sails connecting below to form a secondary arch. The largest sail has 59 curved members, 5 trusses, 20 spreaders, 102 stainless steel bars, 204 rod ends, 40 cables, 40 swage turn buckles, and 20 spreader packs. This impressive architectural icon showcases the skill and craftsmanship that is SME Steel.
