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.
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.
Simpson Strong-Tie is proud to announce that one of our product engineers, Bonnie Yang, Ph.D., P.E., CFS, has been invited to give a public lecture on mass timber connections. The date of her lecture will be March 3 at 11 a.m. PST. Yang’s lecture will be part of a Mass Timber mini-lecture series hosted by the School of Architecture at Mississippi State University in partnership with the Mississippi Forestry Association.
Our Director of International Sales in Latin America, Cyndi Chandler, organized our annual sales seminar in Chile. This was a great opportunity to connect with our engineers and specifiers in Latin America and educate them about the various products and resources we offer. Learn more about this dynamic two-day seminar and the products we demonstrated in Chile.
Simpson Strong-Tie has developed a faster, easier and more economical way to connect CLT and other types of panels on mass timber projects. Introducing the LDSS light diaphragm spline solution, featuring a steel spline strap that replaces traditional plywood splines.
Ryan Edwards eats, sleeps, drinks, and builds with mass timber. Inspired by his work with mass timber, he decided to DIY an outdoor table made from the same material he works with every day. Also, learn what mass timber is all about!
We’ve added two new connectors to our expanding lineup of brackets and straps for mass timber / CLT manufacturers, specifiers and contractors. Introducing the E20/3 angle bracket and MTWS mass timber washer strap.
Both connectors are pre-engineered and code listed for a variety of applications in cross-laminated timber (CLT) and other mass timber projects. Designed to simplify and speed installation, the E20/3 angle bracket and MTWS washer strap are widely available to buy off the shelf, making them a more cost-effective and convenient solution than expensive, custom-fabricated components.
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.
Simpson Strong-Tie has always been a leader in designing innovative products for various construction markets. As an R&D engineer, I enjoy the opportunities for continuous exploring, experimenting and learning that come with my role. There’s never a dull moment working in research and development! At present, I’m thrilled to be part of a team that works on developing products for construction using cross-laminated-timber (CLT) and other forms of mass timber. So I have the honor of introducing three amazing fastener products that are load rated for use in CLT, wood, glulam and structural composite lumber (SCL) products (e.g., LVL, PSL, LSL).
