L.A.’s First Steel-Plate Shear Wall High-Rise
Posted by MSC on December 3, 2008 at 5:16 PM.

AISC recently launched a new web site and portal, www.aisc.org/LA-LIVE, that features the latest information on the L.A. Live Hotel and Residences project, the first steel-plate shear wall high-rise building in Los Angeles.

With eye-catching images of the project site and a live webcam of the structure, the L.A. Live web site showcases the hotel and residences building as the centerpiece of the L.A. Live development, a 4 million-sq.-ft, $2.5 billion downtown Los Angeles sports, residential, and entertainment district development adjacent to the Staples Center and Los Angeles Convention Center. The 56-story structure will house 1,001 hotel rooms and 224 luxury condominiums. The total development cost is pegged at about $1.0 billion for 2 million sq. ft of space.

 

L.A. Live Hotel and Residences broke ground on November 2007, and structural steel erection is expected to be completed by the end of 2008, which is about two months ahead of schedule; the expected opening time frame is early 2010.

 

The idea for the L.A. Live Hotel and Residences structure was born in March 2006, when Nabih Youssef Associates reviewed the conceptual design and suggested replacing the heavy 30-in. concrete shear walls with light 1/4-in. to 3/8-in. steel-plate shear walls to free valuable real estate space; eliminate 35% of the weight of the structure; and reduce seismic design forces and foundation sizes. As a result, the proposal compressed the construction schedule and budget while allowing for more simplified and efficient construction. Nabih Youssef Associates was then hired by the development group, AEG, to convert the 56-story concrete shear wall design to a steel-plate shear wall system solution.
