The American Institute of Steel Construction has updated the industry’s go-to reference for all things seismic design.

The fourth edition AISC Seismic Design Manual expands upon the guidance in the third edition and incorporates the 2022 AISC Seismic Provisions for Structural Steel Buildings, the 2022 AISC Specification for Structural Buildings, and recent design guides.

It’s now available in both digital and print formats.

Parke MacDowell, AIA, sits at the intersection of architectural practice and fabrication--right where people who design innovative structures meet the people who know how to put them together in the real world.

Also at that intersection? The American Institute of Steel Construction’s Forge Prize, which challenges emerging architects, educators, and graduate students to dream big and envision how structural steel will help people live, play, and work in the future.

In the second phase of the competition, three finalists will work hand-in-hand with a steel fabricator to refine their concepts. The winning design will take home a $15,000 cash prize and bask in an industry spotlight.

A steel bridge originally intended only for research in a lab remained strong enough through testing to become a viable real-world structure. In late October, it was officially set in place for an unforeseen second life.

The town of Kent, N.Y., set a 40-ft-long steel bridge as a pedestrian crossing over a small section of Lake Carmel on October 31, solidifying its reuse after serving its purpose as a custom-built research test structure at the University at Buffalo. The bridge has 6-ft girder spacing, is supported by W27x84 sections, and is outfitted with buckling-restrained braces (BRBs)--all as part of a project to test the seismic resilience BRBs could provide in a bridge.
