AMPP Member Reflects on Champlain Towers Efforts: Part 3

In the final column of this three-part series, longtime AMPP member Byron Evetts provides his perspective on the Champlain Towers South recovery efforts and wreckage in the days after the devastating collapse.

How NIST Handles Investigations of Structural Disasters

Tanya Brown-Giammanco, director of disaster and failure studies, explains NIST’s role in investigating structural disasters and why these probes can take years to complete.

Cold Spray Technology Enhances U.S. Army Depot’s Capabilities

Artisans at the Letterkenny Army Depot are now using cold spray technology to perform non-structural repairs, including repairs of corrosion and other surface defects. Cold spray offers additional repair benefits because of a lower operating temperature.

Safety, PPE Considerations for Corrosion Control Projects

Charles S. Brown, PCS—deputy director of coatings at engineering, design, planning, and construction management firm Greenman-Pedersen, Inc.—offers a detailed checklist of safety and personal protective equipment (PPE) considerations when at a jobsite.

New Viscoelastic Coating System Requires Minimal Surface Prep

Viscoelastic coatings are able to instantly bond to surfaces without the need for much surface preparation, nor do they require preheating or curing time. Solutions can be tailored to specific problems by adding additional layers that provide extra protection, depending upon the need.

AMPP Member Reflects on Champlain Towers Efforts: Part 2

In part two of this three-part series, longtime AMPP member Byron Evetts provides his perspective on the Champlain Towers South recovery efforts and wreckage in the days after the devastating collapse.

Susceptibility of Grouted Post-Tensioned Tendon Strands to Embrittlement

There is growing concern that prestressing steel strands within post-tensioned tendons could experience hydrogen embrittlement. One proposed source of hydrogen is galvanic coupling that may exist between the galvanized steel duct and the steel strands.

Michigan Works to Reinforce Bridges with Carbon Fiber Technology

Carbon fiber strands have a tensile strength comparable to steel, but they resist corrosion and require less maintenance over time. Longer service life is the major benefit, according to Michigan Department of Transportation officials.

AMPP Introduces Communities of Interest as New Member Benefit

More formalized than existing groups with moderators and formed under AMPP program committees, professionals can engage with those who share a common interest, demographic, or are from the same geographic area.

Establishing the Chloride Threshold of Stainless Steel in Concrete

Stainless steels differ in terms of corrosion resistance, and the need to determine their corrosion resistance is essential. A standard test method that is reliable, reproducible, and quick is crucial.
