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.

Guides to Making I-Joist Connections — Simpson Strong-Tie® CSGs Make EWP Designs Easier

Connector Selection Guides (CSGs) are tools Simpson Strong-Tie has created to assist users in designing and building with engineered wood products (EWP). They consist of a series of short fliers (available as PDFs on strongtie.com for printing or mobile use) guiding builders on how to select economical and efficient connection solutions — that go beyond IRC prescriptive designs — for the I-joist manufacturer of their choice. Over the years, Simpson Strong-Tie has partnered with EWP makers to develop engineered solutions specifically tailored to the dimensions and characteristics of each manufacturer’s particular products.

Choosing the Right Connections for Wind-Resistant Design

According to the Greek philosopher Heraclitus, “The only constant in life is change.”

When the latest Wood Construction Connectors catalog (C-C-2019) was published, my colleague, Paul McEntee, PE authored an excellent blog post to announce some big changes within the catalog. He shared that Simpson Strong-Tie® was the first in the industry with updated connector allowable load tables to meet the new ASTM test standards required by the 2015 and 2018 International Building Code® (IBC®). It was one of those rare times where being first didn’t exactly feel like winning.

Let me explain …
