In response to the increasing demand for mass timber construction, Simpson Strong-Tie has created mass timber solutions for these builds. These product addition, include our Heavy Seated Knife Plate (HSKP), ACBH concealed beam hanger, and CBH concealed beam hanger. Gain insights into the design, testing, and efficiency of the HSKP in achieving high loads with fewer fasteners. The blog underscores the structural mechanics and the ongoing process of pushing connector limits in mass timber construction.

Introducing AT-3G™: Your high-strength cold-weather, fast-cure anchoring adhesive
In general, post–installed adhesive anchor design per ACI 318 Chapter 17 is relatively straightforward. In practice, however, post–installed anchorage can often become challenging because of fast–track project schedules, supply issues, ever-changing weather conditions, design conflicts/changes, or unexpected field conditions.
From Intern to Aspiring Engineer — My Internship at Simpson Strong-Tie
Meet Anthony Fung, a lab intern at the Karen Colonias Research Lab in Pleasanton, who joined Simpson Strong-Tie this summer to explore the world of testing and research. Throughout his internship, Anthony gained valuable hands-on experience in the lab, deepening his understanding of structural engineering. Additionally, he had the opportunity to engage in activities hosted at our Pleasanton office, providing him with insights into our company culture and the people behind our endeavors.
Mass Timber Diaphragm Options with Four Different Connection Types — How Our LDSS48 Light Diaphragm Spline Strap Evolved
Floors and roofs on mass timber buildings are constructed from large panels of engineered wood, such as cross-laminated timber (CLT) or mass plywood. Designers join these prefabricated panels together on site to create a structural horizontal diaphragm to transfer wind and seismic loads to the vertical elements of the lateral force resisting system. Shear forces between panels must be transferred through these panel-to-panel connections. Conventional wood structural panel sheathed diaphragms have shear capacities and fastener spacing tabulated in Special Design Provisions for Wind and Seismic (AWC SDPWS). Mass timber diaphragms, on the other hand, require some more design work by the designer.
How to Accommodate Misplaced Shearwall Anchorage
For several years, the Simpson Strong-Tie Strong-Wall® research and development team has kicked around the idea of developing an “adapter” that would allow for field substitutions or accommodate misplaced Strong-Wall anchorage.
Meeting Braced-Wall Requirements: A New Portal Frame Solution
In my job I get to travel a fair amount. Between trade shows, sales meetings and field research I think I’ve been to most parts of the country in the last few years. One of the things I hear a lot, particularly in areas governed by wind design, is that the last few revisions of the International Residential Code® (IRC®) impose stricter building requirements. As the product manager for our Strong-Wall® shearwalls, I listen with an ear for braced-wall requirements in these areas. There are quite a few different methods of construction called out in Chapter Six of the IRC, and I think I’ve seen them all used in both single-family and multi-family housing, sometimes with multiple types in one structure!
Questions Answered: CSHP High-Performance Coiled Strap
We recently hosted an interactive webinar in which our new high-performance coiled strap’s product manager, Thom Murphy, and I discussed how an innovative embossment is a game changer for coiled strap, making it easier and faster to install with a standard framing nailer. During the one-hour webinar, we reviewed the benefits of a continuous load path as well as key uses for coiled straps. We also related what was involved in the design and testing of the embossment. If you missed the conversation, you can still watch the on-demand webinar and earn PDH and CEU credits here.

Upgrade Your Coiled Strap: How an Innovative Embossment Takes Utility Straps to the Next Level
CS16 coiled straps. I can’t tell you how many thousands (maybe more) I specified during my time as a consulting engineer. Straps are used everywhere. They were then, and are now, a go-to solution for drag and uplift loads. I didn’t have to look them up in the catalog — I knew the allowable loads by heart.
Then one day at a jobsite, I saw a contractor installing them and thought, “Wow, that is labor intensive. His arm must be so tired!” Suddenly, I felt a little guilty for all of the straps I had personally specified on my projects. I thought there must be a better way. Fast-forward 10 years, and today I’m an R&D engineer for Simpson Strong-Tie, an industry leader that prides itself on offering products that improve construction, keep costs down and allow for a safer built environment. As fate would have it, straps fall into my area of responsibility. Now, thinking about what could be done to improve a flat, steel strap is part of my job. Specifiers use straps load rated based on a National Design Specification® (NDS®) nail calculation and an American Iron and Steel Institute (AISI) steel calculation. How could Simpson Strong-Tie make that better?
Questions Answered: Making the Right Anchor Choice
In this post, we follow up on our August 28 webinar, Making the Right Anchor Choice: Best Practices in Anchor Design, by answering some of the interesting questions raised by attendees.
During the webinar where we discussed the critical performance factors and code requirements you need to consider when designing with or installing adhesive or mechanical anchors. In case you weren’t able to join our discussion, you can watch the on-demand webinar and earn PDH and CEU credits here.
