The Legacy of Loma Prieta

Every year on October 17, we take a moment to reflect on the 1989 Loma Prieta earthquake. The 6.9-magnitude earthquake was one of the most powerful and costly quakes to shake the San Francisco Bay area since the 7.9-magnitude earthquake of 1906. The quake caused an estimated $6 billion in damage and, tragically, resulted in 63 deaths and 3,757 injuries.

Many of those casualties were due to failing infrastructure when sections of the Nimitz Freeway collapsed.

Simpson Strong-Tie was founded in Oakland, California — practically in the heart of the Bay Area. Earthquakes were never far from the minds of our founders. It’s why even before Loma Prieta our mission was to provide solutions that help people design and build safer, stronger structures. However, it’s safe to say the earthquake not only reinvigorated our mission but inspired countless structural engineers who would go on to define the next 30 years of Simpson Strong-Tie research and development into community resilience.

A Day in the Life of a Simpson Strong-Tie Structural Engineering Intern

As I look back on the past year and a half and think about all the madness surrounding Covid-19, I can’t help but feel as if I’m emerging from some strange cosmic time warp. The time that has passed since the early days of the pandemic feels so slow in the moment, yet, when I think about all that has happened in my life during this period, the time has passed by surprisingly quickly.

Building Stronger Stick-Frame Roofs: Code Requirements and Connection Solutions

While stick-frame roofs are sometimes preferred to premanufactured roof trusses in some areas of the country because they can accommodate larger attics, higher ceilings, and complex roof shapes, the code requirements for these roofs are often more complex. That’s largely because, unlike truss-framed roofs, the code needs to provide a complete prescriptive method of building the roof, including the multitude of connections that must be made in the field. And, to complicate matters further, the code requirements for stick-frame roofing have been rewritten in each of the last two code cycles. I’d like to give you a high-level overview of some of those changes. In a previous SE Blog post, we discussed the design concepts of stick-framed roofs, and summarized a few of the solutions offered by the Simpson Strong-Tie® connector system for stick-frame roofing. The main concept in that post was the necessity of a continuous tie across the bottom of the rafter system to prevent the heels of the rafters from spreading under load and pushing out on the tops of the walls.

Questions Answered: Deck Guard Post Connections Webinar

In this post, we follow up on our May webinar, Safer, Stronger Decks: Guard Post Connections, by answering some of the interesting questions raised by attendees.

Dr. Lucy Jones: Mitigation Creates Community Resilience

A Shinto shrine in the Japanese coastal town of Minamisanriku has been the center of its community for centuries. In 1960, a tsunami generated by the great Chilean M9.5 earthquake swept into the ocean bay and damaged the shrine. The priest’s house situated at a higher elevation than the shrine had been spared any damage. The community came together and not only repaired the shrine but moved it up the hill, 50 feet above its previous location, to protect it from future events.

Trainer to the Pros — How Simpson Strong-Tie Educates the Industry

Did you know that Simpson Strong-Tie offers free education and training to the construction industry?

Indeed, we do. For several decades, Simpson Strong-Tie has made a commitment to supporting the development of our industry, and each year we educate tens of thousands of industry pros — engineers, architects, dealers, contractors and building inspectors — about the latest building code updates and best construction practices.

Questions Answered: Deck Ledger Connections for Wood and Masonry

In this post, we follow up on our July webinar, Safer, Stronger Decks: Ledger Connections for Wood and Masonry, by answering some of the interesting questions raised by attendees.

During the webinar we discussed code-compliant ledger connection
options for both wood and masonry construction. In case you weren’t able to join our discussion, you can watch the on-demand webinar and earn PDH and CEU credits here.

Questions Answered: Yield-Link® Connection for Steel Construction

In this post, we follow up on our May 2 webinar, Seismic Resilience and Risk Assessment of the Yield-Link® Connection for Steel Construction, by answering some of the interesting questions raised by the attendees.

During the webinar, we discussed how to achieve seismic resiliency in steel construction with our Yield-Link connection for steel special moment frames and the Seismic Performance Prediction Program (SP3) by Haselton Baker Risk Group. In case you weren’t able to join our discussion, you can watch the on-demand webinar and earn PDHs and CEUs here.

As with our previous webinars, we ended with a Q&A session for the attendees. Jeff Ellis, our Director of Codes and Compliance, and Curt Haselton and Jared Debock, from Haselton Baker Risk Group, answered as many questions as they could in the time allowed. Now we are back to recap some of the more commonly asked questions and their answers. If you’re interested in seeing the full list of questions, click here.
