Structural engineering, like every other research field, advances by educating new generations of students in the principles and practice of the discipline. Knowing that, Simpson Strong-Tie has teamed with the Binational Softwood Lumber Council and the American Wood Council to co-sponsor and coordinate the Timber Strong Design-Build Competition, an annual design contest held at the ASCE Pacific Southwest Conference in Tempe, Arizona.
Engineering students will test their civil and environmental engineering skills this spring when they compete in the annual Timber Strong Design-Build Competition. Eighteen universities will send teams of students to Tempe, Arizona, to participate at the American Society of Civil Engineers (ASCE) Pacific Southwest Conference (PSWC).
The objective of the competition, taking place April 12–14, is to give students valuable real-world engineering design experience:
On February 14, we hosted the third interactive webinar in the Simpson Strong-Tie Composite Strengthening Systems™ Best Practices Series: “Introducing Fabric-Reinforced Cementitious Matrix (FRCM).”
Simpson Strong-Tie engineering manager Brad Erickson, S.E., P.E., and Simpson Strong-Tie senior product manager Mark Kennedy, PMP, conducted an informative discussion of this new product solution. You can view the webinar in our Training Center and take a course to earn one hour of CEUs, PDHs and AIA LU/HSW credits. The course and webinar discuss installation steps, identify projects where FRCM would be ideal, and cite testing and industry standards associated with FRCM.

Designing post-installed anchorage near a concrete edge is challenging, especially since the ACI provisions for cracked-concrete anchorage went into effect. In the following post, one of our field engineers, Jason Oakley, P.E., explains how SET-3G™ and Anchor Designer™ software from Simpson Strong-Tie make it easier to design a ductile anchor solution.
Engineers often provide holdown anchoring solutions near a concrete edge to help prevent overturning of light-frame shear walls during a seismic (or high-wind) event. Sometimes a post-installed anchor must be used if the cast-in-place anchor was mislocated or misinstalled, or is located where a retrofit or addition is needed. Since the cracked-concrete anchorage design provisions went into effect more than a decade ago, it has been challenging for engineers to offer a near-edge post-installed anchoring solution. This is especially true for structures subject to earthquake loads in seismic design category (SDC) C through F. Simpson Strong-Tie’s new SET-3G epoxy is the first anchoring adhesive in the industry to offer exceptionally high bond-strength values that permit ductile anchorage in concrete near an edge. This blog post will cover a specific example that focuses on Chapter 17 of ACI 318-14 to design a threaded rod, anchored with SET-3G adhesive, used to secure a holdown located 1 3/4″ away from a single concrete edge (Figure 1).
Understanding construction loading is important as it relates to the acceptable practices in terms of staging and storing construction materials prior to installation. What does “construction loading” mean? This term describes materials and people that are present during the course of construction. It refers to any construction material that is stacked and/or staged on the trusses for any length of time prior to the installation of said materials. This also includes those individuals that are working or walking on the trusses during the course of construction.
You never know where the next great product idea or innovation is going to come from — some of our best new ideas originate with the customers who use our current products. At Simpson Strong-Tie, we welcome any inspiration that can help us serve our customers’ needs even better. With so much competition, however, and because so much research and testing are entailed in developing each new product, the criteria that an idea must meet to gain eventual acceptance are necessarily quite rigorous. In this post, Steve Rotzin, Manager of Intellectual Property and Legal Services at Simpson Strong-Tie, outlines some of these criteria for your consideration.
All of us, at one time or another, dream up a product idea of some sort. My wife was once sanding the tongue-and-groove boards of our living room ceiling and she thought of a very cool idea of gloves that had Velcro on them and users could interchange sandpaper of various grit on any finger of the glove. If you’ve ever sanded anything, this actually made a lot of sense especially for complex shapes and tough to reach spots. I researched it and found out that someone had already thought of it and “patented it.”
Does everyone do year-end performance reviews to discuss how you did on your project objectives and professional development goals? I love meeting with my team to recap all their amazing accomplishments for the past year, discussing long-term career plans and figuring out the steps we will take to implement those plans over the next six months, year, and beyond. I hate, hate, hate, hate doing all the paperwork that HR requires – but I am done with it now, so I’ll get over it.
One of our new product objectives for 2017 was to create a new fire wall hanger that could be installed before the drywall. Creating a joist hanger that can span a gap while still meeting the target loads was a challenging task. We released the DG series of fire wall hangers in July. I discussed the use of fire wall hangers in Why Fire-Rated Hangers Are Required in Type III Wood-Frame Buildings.
The new FRCM Composite Strengthening Systems™ repair and reinforcement solution from Simpson Strong-Tie combines high-performance sprayable mortar with a carbon-fiber grid that creates a thin structural layer that repairs and strengthens without significantly increasing the structure’s weight or volume. FRCM stands for fabric-reinforced cementitious matrix. Its advantages are similar to those of FRP (that is, strength, low weight and ease of application), but it may also be used to repair, resurface, strengthen and protect in one application, along with providing greater resistance to heat and better long-term durability.

Computer-simulated product testing is being used increasingly in modern engineering and manufacturing because it provides a low-risk, time- and cost-efficient means of modeling system performance using a wide array of variables before a physical prototype has been created. The following Blog post outlines some of the uses and advantages of integrating this technology into the product development process.
The role of test simulation in product design might not be the general focus of the Structural Engineering Blog. However, you may have noticed that computer simulation plots have been cited in a few previous postings. Nowadays, it’s rare to talk about product development without mentioning computer simulation at some point. The aim of this post is to give you a better sense of how test simulation can benefit product development and innovation.
This week’s post was written by James P. Mwangi, Ph.D., P.E., S.E. – our first annual Simpson Strong-Tie Engineering Excellence Fellow with Build Change.
Let me start by wishing everyone a happy holiday season.
My fellowship activities started in July 2017. I spent two weeks in New Jersey getting oriented to the Build Change organization and engineering activities around the world. I then spent two days in Pleasanton getting to meet the engineering team and getting updated on Simpson Strong-Tie products and the team leaders.
