David Huerta, Senior Lab Manager at the Simpson Strong-Tie home office in Pleasanton, California, was present during the renaming of the Karen Colonias Research Laboratory. The lab was renamed in honor of our former CEO, Karen Colonias, who was instrumental in driving our company forward during her 38 years with the company, including 11 as our CEO. David shares his perspective on the lab’s functions and operations, as well as its importance to our company’s legacy.
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.

Strategic Alliance with Structural Technologies Brings End-to-End FRP Solutions to Concrete Strengthening and Repair Industry
Simpson Strong-Tie and Structural Technologies formed a strategic alliance for Composite Strengthening Systems™ (CSS) products in 2021. CSS products include fiber-reinforced polymer (FRP) and fabric-reinforced cementitious matrix (FRCM) strengthening systems. Additionally, where CSS products are not a viable solution, the alliance can also offer recommendations and design for other non-CSS or conventional strengthening solutions. This alliance allows each firm to specialize in their areas of expertise:
Building Connections at Washington State University
In 2021 SImpson Strong-Tie hosted a “Building Connections” symposium at Washington State University. The well-attended event provided our team the opportunity to teach WSU engineering students about the construction industry, common construction methods, our products and our company. Ryan Edwards, Simpson Strong-Tie Senior Business Specialist for Mass Timber and Offsite Construction, co-hosted the symposium and in this blog post reflects on the experience.
