Portrait of Nabih Youssef ’71.

Nabih Youssef ’71

Soon after the 8.8 magnitude earthquake struck Chile in
February, structural engineer Nabih Youssef ’71 MS was on a trek to the South
American nation to carry out a research and reconnaissance mission.

Youssef and his colleagues were eager to discover what
caused countless structures to crumble, while others remained standing tall, in
order to develop more advanced best practices for the field. The Chilean
earthquake, which resulted in the loss of several hundred lives and hundreds of
thousands of structures, ranked as one of the biggest shakes, even causing the
world to spin a bit faster.

“Earthquakes are the biggest research labs,” said Youssef,
the founder and president of Nabih Youssef and Associates, a leading structural
engineering firm in downtown Los Angeles. “It’s where we can truly see the
results of Mother Nature testing our knowledge. In every event worldwide, Mother
Nature gives us something new.”

In Chile, Youssef said, he learned many things. For one,
his confidence in U.S. building codes that separate structural and nonstructural
building components as a means for dissipating energy and strain during a quake
was reinforced. A building withstands more violent and longer periods of shaking
when it can “absorb and roll” with the energy, he said.

Similarly, steel plates—like those used in the newly opened
L.A. Live Tower in downtown—might be a good alternative to reinforced concrete,
providing greater flexibility and movement when shaking occurs.

“You can never overpower Mother Nature, and you can’t
resist earthquakes. You learn to absorb and dissipate them,” Youssef said.

Working in the field of structural engineering over the
last 43 years, Youssef has advanced practices in earthquake engineering, leaving
his mark on structure design throughout the city and the world.

One of his most significant contributions to the industry,
colleagues have said, was enacting performance-based design, a concept that
emphasizes use, purpose, cost-effectiveness and structural soundness from
inception to completion. In the L.A. Live Tower—which Nahib and Associates
worked on—for instance, this approach played an important role in determining
everything from building shape to construction materials.

Youssef and his team’s innovative approach, opting for ¼ inch
steel plates, rather than the standard 36-inch thick reinforced concrete walls,
resulted in a more flexible, light, and budget-friendly building. The tower was
not only completed nearly six months ahead of schedule, but had roughly 27,000
square feet of extra space in hotel rooms, lounges and condominiums, he said.

“It was a great opportunity in my career to capitalize on
the last 20 years of research in the steel plate phenomenon, and take it beyond
analysis and beyond the code,” Youssef said, noting that the city put together a
structural peer review committee to clear the design.

“Above all, we had the ability to design a system that has
a more predictable performance,” he added. “…When you do new avant-garde
solutions, everyone has to buy into the possible risks and buy into the possible

Other buildings which Youssef and his team have worked on
include the retrofit of Los Angeles’ City Hall and the
Our Lady of
the Angels Cathedral
with base isolation—a technique that separates a building from its
base with rubber that absorbs movement and essentially allows buildings to
“roll” in earthquakes. They also renovated the
Los Angeles Coliseum and

, worked on the expansion of the J. Paul Getty Museum Villa, the
Skirball Jewish
Cultural Center
, and aided in the construction of
Stanford Hospital.

Prior to starting his own firm in 1989, Youssef also worked
on the Moscow World Trade Center and structural engineering projects for the
Shah of Iran, among other things.
