The mortar resists microcracking through in situ crystallization of platy strätlingite, a durable calcium-alumino-silicate mineral that reinforces interfacial zones and the cementitious matrix. The dense intergrowths of the platy crystals obstruct crack propagation and preserve cohesion at the micron scale, which in turn enables the concrete to maintain its chemical resilience and structural integrity in a seismically active environment at the millennial scale. — Berkeley Lab
From skyscrapers and bridges to residential and heritage projects, the annual Structural Awards recognize the best in structural engineering excellence and the significant role that structural engineers worldwide serve. Out of this year's shortlist, 12 projects were awarded at the award ceremony in London. Winning the Supreme Award for Structural Engineering Excellence went to The Glass Lantern at the Apple Store in Istanbul. — bustler.net

It's that time of year again. The Institution of Structural Engineers revealed the 2014 shortlist for their annual Structural Awards today. The awards recognize achievement, innovation, and excellence in the field of structural engineering in addition to promoting its significant role in the creation of inventive design solutions. — bustler.net
In partnership with 3D Systems, Arup used 3-D printers capable of fusing powdered steel to replace the clunky, welded assemblage of plates that made up the original design. The result is a streamlined part: 15-percent lighter than its conventionally fabricated forebear and 1,000 times cooler-looking. — wired.com
The Structural Awards, held by the Institution of Structural Engineers every year, recognizes the range of innovation, achievement, and excellence of structural engineers whose work is often overlooked. The Structural Awards highlights the challenging environments structural engineers constantly face in order to help build highly complex structures. The annual competition aims to distinguish talent, garner public attention, and inspire young people to explore the field of structural engineering. — bustler.net
After 2,000 years, a long-lost secret behind the creation of one of the world’s most durable man-made creations ever—Roman concrete—has finally been discovered by an international team of scientists, and it may have a significant impact on how we build cities of the future. — businessweek.com

The Watts Towers in South Los Angeles will be the subject of a new study conducted by experts from UCLA to determine the stability of the historic sculptures, which were completed by Simon Rodia in 1954. The study, now underway, is expected to be completed by early next year. — latimes.com
In the same way that structural deficiencies can be detected with something solid, two engineers from Brigham Young University--Brian Mazzeo and Spencer Guthrie--are listening in for the tell-tale acoustics by splashing bridges with water. They're looking for something called "delamination." — popsci.com
After seven years of teaching structures to a mixed group of architecture and structural engineering graduate students at MIT, Paul Kassabian found that many of his future architects took a just-enough-to-get-the-homework-done approach to understanding those fundamental components. So he created an app to help them out. — fastcodesign.com
“The form was reinvented to an extent,” says Yanni Loukissas, a postdoc in MIT’s Program in Science, Technology, and Society (STS). And while the question of exactly which design changes should be credited to Utzon or Arup’s firm has been a matter of some dispute, the building, Louskissas says, stands as “an example where the engineer was instrumental in reshaping the project.” — web.mit.edu
Last quarter a group of Cal Poly Pomona architecture and structural engineering students with professors Axel Schimitzberger and Dr. Mikhail Gershfeld conducted a multi disciplinary studio to design prototype tsunami evacuation facilities. The purpose of the studio was to design a temporary...
