Modern-looking cable system offers curtainwall support

Ronstan Tensile Architecture, Portsmouth, R.I., provides a sleek cabling system to help support 20,000 square feet of glass curtainwall inside the JW Marriott Hotel at L.A. LIVE, part of a new cutting-edge tower built for the premiere entertainment campus in Los Angeles.

Ronstan Tensile ArchitectureServing as the main hub for L.A. LIVE, the tower stands 54 stories tall, making it the first skyscraper in L.A. to reach such heights in two decades. While JW Marriott is the focal point of the complex, a Ritz-Carlton Hotel, the Residences at the Ritz-Carlton condominiums, and the Nokia Plaza all share the space.

The high-profile brainchild of world-famous Los Angeles-based Gensler architects, the new L.A. LIVE complex features the stainless-steel truss system that laterally braces the JW Marriott lobby curtainwall. The system is composed of Ronstan's ACS1-SS and ARS1-SS rods and turnbuckles, which employ Ronstan cabling to uphold segments of the south-facing glass façades in a corner-tocorner fashion.

The resulting design is a vertical tower of graceful crisscrossing cable patterns, providing delicate accents to the glass and an engaging geometrical pattern without inhibiting views of the outside. Ronstan provides further lateral support on the north- and west-facing glass walls with horizontal bracing cables. The modern-looking system complements the aesthetic of the lobby, which itself pays special attention to geometry, balance and contemporary style.

The Ronstan-supported curtainwall was designed, engineered and installed by Enclos Corp., San Juan Capistrano, Calif. Nabih Youssef Associates, Los Angeles was the general engineer and Webcor Builders, Los Angeles, was the general contractor. The project was completed in 2009.
