The Engineering Behind San Francisco's Safest Building

09:30 - 28 July, 2018
The Engineering Behind San Francisco's Safest Building, For 181 Fremont, Arup’s radical move was to do away with plans for a tuned mass damper or a sloshing damper on the skyscraper’s roof—common features in tall towers in the U.S. for reducing the natural sway of buildings. Neither damper style goes very far in protecting a building against seismic force, says Ibbi Almufti of Arup. Image Courtesy of Kevin Chu/KCJP

This article was originally published by Metropolis Magazine as "The Skyscraper's Innovative Structure is Changing the Game for Earthquake Design".

The most remarkable thing about 181 Fremont—San Francisco’s third-tallest tower, designed by Heller Manus Architects—is not the penthouse’s asking price ($42 million). Rather, it’s an innovative yet unglamorous structural detail: a viscous damper system that far exceeds California Code earthquake-performance objectives for buildings of 181 Fremont’s class, allowing immediate reoccupation after a seismic event.

Global commerce and the unprecedented demand for travel and have resulted in the proliferation of airports around the world. In their short history, terminal buildings have been criticized for employing generic architectural forms that are unapologetically disconnected from their context and cultural identity. Technical complexity and functional design have often taken precedence over quality and comfort for users.

The goal of the competition is to shed new light on the meaning and value of tall buildings in modern society. The deadline for submission is July 23, 2018.

The age of the tall building as a single iconic piece of sculpture, standing in isolation from its surroundings, is coming to an end. Designers have a responsibility to ensure that these permanent urban structures engender a future-oriented urban response to the greatest challenges of our time: unprecedented population growth; mass

7 Myths in Architectural Detailing that Are Changing in the Digital Age

7 Myths in Architectural Detailing that Are Changing in the Digital Age

The recent availability of automated design and production techniques is changing the development of building details. With parametric and algorithmic design methods and the use of digital fabrication, new abilities are required from architects for the design of details, at the same time as new players are beginning to take part in their development.

Although not always given the necessary attention, architectural details are of extreme importance for many aspects of a building. They can define its theoretical expression and technical character, and impact its production process, its assembly method and even its ecological footprint. Contemporary architecture shows a new interest in detailing, which should not be confused with a return to the appreciation of artisanal work.[1] This new interest is related to the recent re-involvement of the architect with the physical making of buildings, as a result of the use of digital technologies.[2] The new “digital master builder” [3] counts on file-to-factory processes, in which the morphology of construction details is directly related to the knowledge of the available production processes.

At a time when engineers, designers, and builders must find solutions for a resource-constrained environment, new wood technology, materials, and science are accelerating efforts to enhance safety and structural performance.

International Building Code requires all building systems, regardless of materials used, to perform to the same level of health and safety standards. These codes have long recognized wood’s performance capabilities and allow its use in a wide range of low- to mid-rise residential and non-residential building types. Moreover, wood often surpasses steel and concrete in terms of strength, durability, fire safety, seismic performance, and sustainability – among other qualities.

Increasingly close collaboration between architects and engineers has caused an explosion in bridge design over the last few decades, resulting in structures that are both bold yet rational. As a result, cities have exploited bridges as great monuments of design, to foster pride in the residents and promote themselves as a destination for tourists. These ideas have inspired photographer Greig Cranna as he travels the world, capturing the elegance of today's bridge infrastructure.

Cranna has been documenting some of his stunning photography on Instagram, collating it over the past 20 months into a forthcoming book, Sky Architecture—The Transformative Magic of Today's Bridges. In capturing these entrancing structures, the photos show the impact of the bridges as an addition to the landscape and revel in their contemporary silhouettes and designs.

Behind the Tech That Moves 2 Million People During The Hajj

09:30 - 6 October, 2017

Every year, 3 million Muslim pilgrims from over 120 different countries travel to Makkah (commonly transliterated as Mecca), Saudi Arabia, to perform Hajj (pilgrimage) in the Islamic month of Zilhaj. Due to the ever-increasing number of visitors each year, overcrowding has led to deadly accidents and stampedes in the past; to ensure crowd safety and better circulation, the Makkah Development Authority (MDA) engaged Otis, one of the world’s leading manufacturers of people-moving products, and successfully oversaw the redesigning of the Jamarat Bridge.

Watch the video above for a summary of the architectural design of the Jamarat Bridge, or read on to see a 7-minute mini-documentary about the structure's development.

As reports have emerged that San Francisco’s infamous sinking skyscraper, the Millennium Tower, is continuing to settle downward, engineers from LERA and DeSimone Consulting have unveiled a potential fix for the building’s woes.

Since construction began in 2005, the 58-story luxury condominium tower has sank approximately 17 inches downward and while leaning 14 inches to the North. And according to a new report from Arup Ground, the issue doesn’t appear to be resolving itself anytime soon: in the past 7 months alone, the building has sunk an additional inch and tilted a further two inches, causing cracking in the building to worsen.

Triggered to action, developer Millennium Partners brought in LERA and DeSimone to devise a solution that would return the building to its original siting and secure it against sinking, all while allowing the building to continue operating through the repair process.

Charles Thornton, one of the world’s preeminent structural engineers, once said that the greatest challenge facing the profession of structural engineering is that “I don’t think we have enough self-esteem and enough confidence in ourselves to believe that what we do is so important... Architects are trained to present, to communicate, to sell, to promote themselves, to promote their industry, and to take credit for what they do.”

As a structural engineer with over a decade of experience, I agree with Mr. Thornton—to an extent.
