TIANJIN WORLD FINANCIAL CENTER TIANJIN, CHINA

structural engineer | Skidmore, Owings & Merrill LLP

the 1,100 ft tall tianjin World Financial center tower, situated at the

historical heart of tianjin, captures the city’s powerful confluence of history,

culture, geography, and art. With the tower’s slender form, and tianjin’s

long history as the ancient entry port to china and a major center for ship

building and steel production, steel plate shear walls were chosen as major

components of the tower’s lateral-force -resisting system.

to satisfy the requirements of both chinese and uS codes, a unique system

of “buckling restrained” stiffened steel plate shear walls was developed,

and validated in depth using advanced analytical studies as well physical

modeling and testing.

J U R Y C O M M E N T

The Jury commented that the project does indeed “create a nuanced public place that embodies the city’s international prominence as a physical and economic gateway to China.” One of the Jury panel members, born in Shanghai, noted

with emphasis that “they are using historicism in the cultural references embedded in the integrated design” – now we know

what a “Landmark” building is!

UNIVERSITY OF CALIFORNIA, SAN FRANCISCO, RAY AND

DAGMAR DOLBY REGENERATION MEDICINE BUILDING

structural engineer | Nabih Youssef Associates - Structural Design Engineer

Forrell/Elsesser Engineers, Inc. - Design-Build,

Structural Engineer of Record

the new ray and Dagmar Dolby regeneration Medicine Building, located

at the university of california, San Francisco’s Parnassus Medical campus,

houses new laboratories for the university’s stem cell research program.

the new 70,000 square foot laboratory and medical facility houses 25

Principal investigators and their teams studying tissue development and cell

based approaches to treating disease.

nabih Youssef associates with rafael Viñoly architects; and Forell/

Elsesser Engineers, inc. with Smithgroup architects and DPr construction

(Design-Build team) collaborated to develop a design that responded to the

demanding and steeply-sloping site, that curves and slopes up to 65 degrees,

ultimately creating a 700 foot long serpentine-shaped building. the teams’

integration of architecture and engineering, on an essentially un-buildable

piece of land, viewed the site constraints and architectural program

demands as both a unique design challenge and opportunity. to achieve the

owner’s desire for seismic performance beyond basic code compliance, a

“triple” Friction Pendulum isolation bearing system was integrated into

the triangular space frame support structure. Furthermore, the design-

build engineer developed, tested, and implemented a unique dynamic uplift

restraint device to address the narrow building’s tendency to uplift during

an earthquake.


The Jury commented that in recognizing the importance and achievement of design excellence of the project, it moved the

entry from the “New Construction” category to “Landmark” status. This amazing project’s “Integrated Project

Delivery” method was successful in controlling costs and schedule for the University – completing construction in just

two and one-half years after the design-build contract was awarded.

CYCLISK

SANTA ROSA, CA

structural engineer | ZFA Structural Engineers

the result of a design competition using recycled materials, the cyclisk

was designed by artists Mark grieve and ilana Spector. the project is a

65 foot traditionally shaped obelisk made from discarded bicycles. the

artists collected 340 unusable bicycles from all over california to create

the four-inch-thick skin of this large landmark structure. the cyclisk was

constructed using an efficient steel-trussed superstructure designed to be

both light-weight and efficient using readily available structural steel angles

and reinforced connections. the unusable bicycles were cleaned, then

welded together and attached to the superstructure to create the obelisk

form. the $37,000 community art piece was commissioned by the city of

Santa rosa for Santa rosa nissan as a part of its “art in Public Spaces”

program.


The work demonstrates a straightforward collaboration between artist and structural engineer. While the Obelisk has

marked public space for millennia, the “Cyclisk” is a unique interpretation of monumental public art.

which antiquity meets high-tech seismic design. it consists of two domes

– totaling 40,000 pounds – that sit atop a state-of-the-art base-isolated

platform designed for seismic safety. the temporary structure housed

various artistic performances and workshops during its run at the Yerba

Buena center for the arts. the tile-vaulted masonry domes are homage to

ritualistic bowls used in ancient Babylon 1,500 years ago. the platform,

supported by 30 Ball-n-cone seismic isolators, was designed employing

unconventional full-scale testing methods in lieu of traditional testing and

served as an alternate means of code compliance while accommodating the

project’s aggressive schedule and budget.


The Jury commented that the completely re-useable, multi-media art installation features a very innovative structural system and a pretty clever testing procedure. The project

demonstrated a collaborative design and approval process for all involved – The City + Artist + Structural Engineer.

UC BERKELEY BOWLES HALL RETRO FIT FOR HAYWARD FAULT OFFSET

BERKELEY, CA

structural engineer | Rutherford & Chekene

Bowles Hall is the oldest dormitory at the university of california, Berkeley

campus. built in 1927. the building is a tudor style mansion of seven floors

that steps up the slopes of the Berkeley hills. in a study commissioned by

the university, geologists found that two corners of the building sit atop

a potentially active “western trace” of the Hayward fault. to mitigate

the potential hazard of the ground beneath the building moving several

feet along the rupture zone of the fault, a unique retrofit solution was

implemented allowing for large ground movements to occur without causing

significant damage to the building.


The Jury commented that for this historically important building, the design “eliminated the problem” rather than to try

and solve it by brute force – very creative thinking.

the ramos Sherry House and Depot Saloon constructed circa 1880 in St.

Helena, california are often described as historic jewels and were recently

nominated to the national register of Historic Places. as part of the

preservation and revitalization of this historic site, the goal was to make

each building structurally sound, accessible, and designed to meet 21st

century needs without disturbing the historic and aesthetic architectural

fabric. requiring creative engineering solutions, the seismic upgrade

included reinforcement of the existing stone walls utilizing pressure

injection grouting techniques, as well as, strengthening of the existing floor

and roof diaphragms.


The Jury commented that the design is both “tough” and “delicate” demonstrating as restrained approach as reasonably

possible! The structural design could have been much heavier handed.

SEISMIC RETROFIT - CORE BART SYSTEM WEST OAKLAND AERIAL STATION OAKLAND, CA

structural engineer | Creegon + D’Angelo Infrastructure Engineers

in 2002, San Francisco’s Bay area rapid transit (Bart) system developed

a $1.2 billion Earthquake Safety Program charged with assessing system

wide vulnerability and expected performance under major earthquakes.

the program provides upgrades using performance-based earthquake

engineering standards to improve the structural integrity of Bart facilities

with the goal to protect public safety, return Bart service quickly and

avoid highway gridlock after a major earthquake.

comprehensive evaluations of existing Bart facilities involved engineering

and statistical analyses, developing scenario earthquakes, computer models,

damage predictions, upgrade options, and cost-benefit analyses. Primary

upgrades at the West Oakland Station, the last station prior to westbound

trains entering the transbay tube, included enlarged and reinforced concrete

foundations/beams, fiber-reinforced polymer wrap jackets around concrete

columns, and additional shear keys.


The Jury commented that the West Oakland Station project, and the program as a whole, represents an excellent example of designing to achieve resilience following major earthquakes engineered to an “Operational Performance Level” under a design basis 500-yr return period event – “Infrastructure” at its best!

BULGARI FLAGSHIP STORE

SAN FRANCISCO, CA

structural engineer | Holmes Culley

While “Bulgari” is known the world over for high fashion fine jewelry,

watches, handbags and accessories, their existing 10,000 square foot retail

space, located in a 1986 reinforced concrete building in union Square, San

Francisco was a dark, confusing maze of stairs, ramps and low ceilings in

three split levels. Working with an international design team, the retrofit

includes an extensive structural alteration of the building’s lower stories

providing a new four-level store with open atria, accentuated by a glass

elevator, four separate glass-tread stairways, and an architecturally exposed

horizontal truss. the retrofit maintained the building’s structural integrity

and compliance with current seismic code provisions while allowing for the

“Bulgari” brand to shine through.


The Jury commented that the brand name retail store retrofit is an excellent example of transforming an existing building

into a high-profile design focus – utilizing the horizontal steel trusses and making them a design feature was a very

innovative way to open up the space.

GUIDELINES FOR PERFORMANCE-BASED

SEISMIC DESIGN OF TALL BUILDINGS

structural engineer | Pacific Earthquake Engineering Research Center

PEEr started the tall Buildings initiative to develop performance-based

approaches that would enable tall building construction to reach new

heights while also ensuring safe, usable tall buildings following future

earthquakes. in november 2010 PEEr achieved this goal by publishing

and releasing its “guidelines for Performance-Based Seismic Design of

tall Buildings.” the guidelines present a recommended alternative to the

prescriptive procedures for seismic design of buildings contained in aScE

7 and the international Building code. these guidelines demonstrate how

the earthquake engineering profession can be enhanced by openly and fully

engaging both designers and researchers in a mutually beneficial project.

“The Jury comments were spirited and vigorous. A Jury senior statesman noted that although “controversial” the non-prescriptive guidelines made contributions that were

“solomonic” which he clarified as “exhibiting or requiring the wisdom of Solomon in making difficult decisions”.

The Jury further noted that the spirit of the work is great – addressing real earthquakes and real performance – a very

useful and valuable “living document”.”
