Modern curtain wall systems require structural supports as strong as they are versatile to keep pace with today’s increasingly large free spans, challenging angles, and sophisticated glass-clad aesthetics. While steel curtain wall frames have long met strength criteria, they have only recently provided the necessary design flexibility.
A two-story glass lobby featuring a thermally advanced curtain wall is the focal point of the Clark Visitor Center in Williamstown, Massachusetts. Designed by Pritzker Prize-winning architect Tadao Ando, the new building is part of the Sterling and Francine Clark Art Institute’s 15-year, $145-million expansion.
Structurally reinforced insulated glass curtain wall assemblies are front and center in the design of California’s Anaheim Regional Transportation Intermodal Center (ARTIC). Owned and built by the city, this three-story, parabolic, long-span, grid-shell structure creates a welcoming space with open circulation and a light-filled atrium.
Skyscraper cities, while conceptually rooted in mid-20th century architecture, are being reinvented to appeal to a new generation—and a new market. Their design is a topic of enduring interest in the world of architecture. The latest trend of supertall structures is defined by The Council on Tall Buildings and Urban Habitat (CTBUH) as taller than 300 m (984 ft).
