Duplex Stainless Steel Revolutionizes Structural Design

duplex_San Diego 01-Cropped Kaplan

Architectural and engineering firms are increasingly exploring stainless steel’s possibilities as a structural material as new research, structural codes, and design guides become available. Most designs have used the familiar Types 304L or 316L alloys from the austenitic family of stainless steels, but for all but the lightest sections, the duplex stainless steel family presents a much greater potential for innovation.

Weighty Matters: An overview of in-situ load testing

featured`

In-situ load testing is a powerful tool to assess the performance of structures with respect to their ability to carry code-prescribed loads. The practice dates back to the late 1800s and has been used to verify the load rating of structures, as well as the expected performance of structures in retrofit, repair, and strengthening applications.

The Benefits of Metal Roofs and Coatings

featured1

Recognized as sustainable, durable building components, metal roofs are used in various applications. The performance of the assembly’s panels depends on the metal substrate, metallic layer, and exterior coating. These are critical to the panel’s weather and corrosion resistance, color retention, and overall longevity.

Specifying Structural Framing Systems

DSC_0856

Many factors come into play when designers specify structural framing. There are so many criteria, sometimes there is no absolute answer as to which framing system would perform best. At the same time, the interests of various parties must be served, meaning the final selection does not always rest with the structural engineer.

During the medieval period, complex Gothic structures were built from drawings that communicated a designer’s overall vision without detailing specific means of construction. Master craftsmen translated designs into buildable structures using simple tools available at the time. Now, in some respects, the construction industry has come full circle.
