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.
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.
During the webinar we discussed the minimum code requirements for railing posts and their connections, and the code-compliant connection methods: holdowns, deck tension ties, Strong-Drive® structural wood screws, and through-bolts.

As with our previous webinars, we ended with a Q&A session for the attendees. Our R&D engineers Scott Fischer and Rachel Holland answered as many questions as they could in the time allowed. Now we’re back to recap some of the commonly asked questions and their answers. Continue Reading
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.
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.
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.
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.

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.
Brick or masonry veneer has traditionally posed a problem to homeowners and contractors seeking to attach a deck to a home without removing large portions of the veneer or siding. No longer is that the case, thanks to the innovative BVLZ brick veneer ledger connector from Simpson Strong-Tie. In this post, Rachel Holland, P.E., an R&D structural engineer at Simpson Strong-Tie, explains the research and insights that went into testing and developing this revolutionary connector.
Flooding is one of the few natural disasters that occur commonly throughout all regions of North America. The causes of floods can differ depending on the region, but the impact is nearly always the same. Recent floods have caused billions of dollars in damage annually to structures near the coast as well as inland.
