# Nabih Youssef

Nabih Youssef, S.E., F.A.S.C.E (May 29, 1944 – July 12, 2024) was an American structural engineer, most recognized for his work in seismic engineering. Youssef is recognized for translating academic structural engineering concepts into practical applications, most notably through the base isolation technique employed in the Los Angeles City Hall renovations. His significant achievements also include advancements in Performance-based building design and the use of a Steel plate shear wall in areas of high seismic risk.

## Education and working life

In 1967, Youssef received a B.S. in Structural Engineering from Cairo University. After emigrating to the United States he received a M.S. from C.S.U.-L.A. and then a postgraduate Diploma in Earthquake Engineering from U.C.L.A.
Youssef led the engineering division at A.C. Martin Partners before founding his own firm, Nabih Youssef & Associates (NYA), in 1989.

## Notable projects
### L.A. Live

The first of the 55-story L.A. LIVE's three development phases was completed late 2007 when the doors opened at Microsoft Theater, a 7,100 seat concert and awards show venue. Xbox Plaza (formerly Microsoft Square), a 40,000 sq. ft. open air space, featuring six 75-foot-towers with LED and static signage along with 1,500 parking spaces also debuted in phase one. It uses an advanced steel plate shear wall system to resist lateral loads and is the first building in California to do so.
The second phase began in late 2008 with The Novo (a 2,300 person venue), the Conga Room, Lucky Strike Lanes & Lounge, The GRAMMY Museum® and 2,000 more parking spaces. Restaurants opened throughout phase two, with all 13 eateries completed in 2009. Another notable phase two event was the first live broadcast from the ESPN West Coast Broadcast Center.
The last and final phase was completed in late 2009 with the grand opening of the 14-screen Regal Cinemas and in early 2010 with The Ritz-Carlton Hotel, Los Angeles, the JW Marriott Los Angeles L.A. LIVE and The Ritz-Carlton Residences at L.A.
