As introduced in Part 1 of this three-part series, the Oregon State Capitol Renovation project goal is to seismically retrofit and renovate multiple structures utilizing ASCE 41 (see the March 2024 issue). The importance of preserving the historical Capitol increased after losing the original and second state Capitol buildings to fires. While the original design of the 1938 capitol was fire resistant, structural damage incurred during the 1993 Scotts Mills earthquake prompted the Oregon Legislature to enhance the seismic resiliency of the entire Capitol complex.

Artificial Intelligence (AI) has the potential to revolutionize the structural engineering profession. However, several obstacles must be addressed before AI can be fully integrated into practice. These challenges include a lack of vision or roadmap for AI’s impact on the industry; slow adoption of new technology; concerns about accuracy, risk, data privacy, and ethics; and the need for education and innovation. The National Council of Structural Engineers Associations (NCSEA) Foundation launched an Innovation in Structural Engineering (ISE) grant to lead the profession in embracing AI to revolutionize and empower structural engineers to be leaders in responsibly shaping the future of the built environment.

The wildland-urban interface (WUI) is where structures or other human development interfaces or intermixes with wildland vegetation. Today, many WUI communities are being threatened by fire or consumed by it. To understand how this predicament came to be with respect to wildfire impacts on communities, the policies and mitigation practices of the past must be understood. At the beginning of the 20th century, the U.S. enacted policies that stipulated fires should be put out immediately within the wildland to protect timber crops. These policies were in reaction to the Big Blowup of 1910, which consisted of over 1,700 fires across Idaho, Montana, and Washington, burning more than three million acres of federal and private land and killing at least 85 people. These fires were estimated to have destroyed about 7.5 billion board feet of timber.
