Purdue research buzzing about construction lessons taken from bees, honeycombs
Nikhilesh Chawla, the Ransburg Professor of Materials Engineering at Purdue University, and Rahul Franklin, a graduate research assistant in materials engineering, prepare to examine a honeybee comb sample with a 3D X-ray microscope at the Flex Lab in Discovery Park. Examining the combs has uncovered new techniques used by the bees that could translate into new building concepts.

AISC Releases Buy Clean Guidance to Help Legislators Maximize Structural Steel’s Unmatched Sustainability
CHICAGO - Hot-rolled structural steel is the greenest structural material on the market, thanks to its unsurpassed recycled content and ability to be recycled into new steel, over and over again, with no loss of properties. It's an obvious choice for the Buy Clean movement, which advocates for environmental properties that encourage the use of products and materials with a smaller carbon footprint. But the industry is complex. That's why the American Institute of Steel Construction has rel...
Transbay Study Group Makes Recommendations
CHICAGO - The American Institute of Steel Construction’s ad hoc task group on Transbay has wrapped up its work and made its recommendations to the AISC Committee on Specifications. The group was formed after cracks were discovered in steel members in the newly opened Transbay Transit Center in San Francisco. It’s expected the report will lead to a number of changes in future steel specifications. “The task group presented a holistic set of proposals dealing with fracture toughness, sharp disc...

Updated ASCE Publication Provides Guidance on Anchorage Design for Industrial Facilities
Reston, Va. – Anchorage design involves connecting a structural or non-structural component to a concrete or steel structure. Understanding the state-of-the-practice for the design of cast-in-place anchors, welded anchors, and post-installed anchors is critical when used for petrochemical and other industrial facilities. The latest American Society of Civil Engineers (ASCE) publication, Anchorage Design for Petrochemical and Other Industrial Facilities, Second Edition, serves as a source for uni...
Slab Production The Easy Way in Norway
Leading precast concrete producer Contiga’s new hollow core plant on the isle of Askøy is taking process automation to a new level. Just 10 operators. That’s all it takes to complete three 132m long hollow-core concrete slabs every day at Norwegian precast producer Contiga’s state-of-the-art new facility on the Island of Askøy. Skilled labour is both scarce and expensive in Norway, so a priority in the plant’s design was to incorporate the highest level of automation possible. Contiga,...

Why Precast Is Central to Cutting Concrete's Carbon Footprint
With the ability to cut CO2 footprint by 25% factory-based precast concrete production has the potential to save billions of tons of CO2 being emitted each year. So why is it so overlooked, asks Mats Jungar, CEO of Elematic? The world has a love-hate relationship with concrete. On the positive side the raw materials for concrete are plentiful, and the production of concrete foundations and structures are extremely cheap. But on the negative side concrete’s contribution to global CO2 o...
