Top Five Most Downloaded Engineering Letters

Prior to joining Simpson Strong-Tie, I spent 13 years working as consulting structural engineer. As a specifier, I was amazed at the number of resources Simpson made available to me. From software, to blogs, to design guides, there were many resources to help me solve problems and streamline the design process. One resource that can sometimes be overlooked is the numerous engineering letters Simpson Strong-Tie engineers have authored to assist in the use of our products.

Empowering Future Engineers: Cal Poly Students’ Journey in the Timber-Strong Design Build Competition

The Timber-Strong Design Build℠ (TSDB℠) Competition is an annual event sponsored by the the American Society of Civil Engineers (ASCE) in partnership with the American Wood Council (AWC), APA (the Engineered Wood Association), and Simpson Strong-Tie in which student teams design and build an artistically creative two-story wood light-framed buildings that are sustainable, aesthetically pleasing, and structurally durable. The competition enables students to gain experience in common structural engineering design as well as the business management and building practices used in construction environments. The authors of this article are graduating civil engineering students in the Civil Engineering program at California Polytechnic State University in San Luis Obispo, CA.

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.
