A couple of years back we hosted a “Take your daughter or son to work day,” which was a great opportunity for our children to find out what their parents did. We had different activities for the kids to learn about careers and the importance of education in opening up career opportunities. People often ask me what I do for Simpson Strong-Tie and I sometimes laugh about how my son Ryan responded to a questionnaire he filled out that day:
Q. What is your mom/dad's job?
A. Goes and gets coffee and sits at his desk
Q. What does your mom/dad actually do at work?
A. Walks in the test lab and checks things
When I am not checking things in the lab or sitting at my desk drinking coffee, I manage Engineering Research and Development for Simpson Strong-Tie, focusing on new product development for connectors and lateral systems.
I graduated from the University of California at Berkeley and I am a licensed Civil and Structural Engineer in California. Prior to joining Simpson Strong-Tie, I worked for 10 years as a consulting structural engineer designing commercial, industrial, multi-family, mixed-use and retail projects. I was fortunate in those years to work at a great engineering firm that did a lot of everything. This allowed me to gain experience designing with wood, structural steel, concrete, concrete block and cold-formed steel as well as working on many seismic retrofits of historic unreinforced masonry buildings.
Good Ideas Come from Many Places — “Necessity Is the Mother of Invention”
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.”

How Computer Simulation Can Power Innovation
This week’s post was written by Frank Ding, Engineering Analysis & Technical Computing Manager at Simpson Strong-Tie.
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.

Simplify Access to Your Drawings with the Simpson Strong-Tie AutoCAD® Plugin
This week’s post was written by Carolyn O’Hearn, Software and App Marketing Manager at Simpson Strong-Tie.
Accessing engineering drawings, determining whether you have the right ones and loading them into AutoCAD can seem like an exhausting endeavor. Wouldn’t it be nice to have an application that does everything you need in one package? An application that will also save you time, on both retrieval and installation, and give you access to additional applications? Simpson Strong-Tie has developed a new tool that can take care of all these needs.

Turkeys and Gratitude
This week’s post was written by Kari Martin, Marketing Communications Content Manager at Simpson Strong-Tie.
There are a couple of turkeys that like to hang out around our home office in Pleasanton and, no, I’m not referring to any of my colleagues — we actually have a gang of wild turkeys that comes up from the creek behind the office. Almost every day, these colorful birds feel safe enough to stroll onto the office walkway pecking for food outside our office windows and doors. It’s surprising to me that these beautiful creatures could be so fearless (or is it simply naïve?), especially around Thanksgiving time. Their presence reminds me that being fearless is important, because nothing new would ever be discovered if we were too afraid to venture outside our comfort zones.
The beauty and strangeness of the turkeys also remind me to be thankful, because everything we have in life is ultimately a gift. Their consistent return to our office is a gentle reminder as I walk into work to give thanks to you, our readers, our customers and our partners every day. Thank you!
We hope you enjoy the holiday with your family and friends. We’ll be back with another post next week.
A New Way to See Whether FRP Is Right for Your Project
This week’s post was written by Griff Shapack, FRP Design Engineer at Simpson Strong-Tie.
Specifying our Composite Strengthening Systems™ (CSS) is unlike choosing any other product we offer. In light of the unique variables involved with selecting and using fiber-reinforced polymer (FRP) solutions, we encourage you to leverage our expertise to help with your FRP strengthening designs. To get started, we first need to determine whether FRP is right for your project. The fastest way to do that is for you to fill out our Design Questionnaire. Our new Excel-based questionnaire collects your project information and helps you use the existing capacity check to evaluate whether or not FRP is suitable for your project per the requirements of ACI 562-16 Section 5.5.2. After the feasibility study, the questionnaire creates input sheets specifically for your project.

Drop, Cover, and Hold On – Becoming Earthquake-Smart in the 2017 Great ShakeOut
This week’s post was written by Jacob McAuley, Associate Regional Marketing Manager at Simpson Strong-Tie.
Every October, millions of people across the globe participate in earthquake drills as part of an event called the Great ShakeOut in order to improve their earthquake preparedness. This year, the Great ShakeOut took place on October 19 and involved more than 60 countries. In addition to the earthquake drill, participants in the event often take part in other activities such as seminars, Q&As and more. At Simpson Strong-Tie, we practiced earthquake drills at each of our major branches, and, in our Pacific Northwest region, we were part of a Reddit Ask Me Anything event (an online live Q&A) to talk about earthquake safety and answer people’s questions. Below, I discuss our participation in both of these activities.

Introducing the New and Improved Simpson Strong-Tie Strong-Wall® Bracing Selector
This week’s post was written by Caleb Knudson, R&D Engineer at Simpson Strong-Tie.
It’s been said that the World Wide Web is the wave of the future. Okay, maybe this is slightly outdated news, as it’s been 25 years since Bill Gates penned his internet tidal-wave memorandum, but it’s a good lead-in to this week’s blog topic – web apps. More specifically, those apps that have been developed to address the wall-bracing requirements defined in the International Residential Code® (IRC). Designers and engineers have no doubt noticed that over the last several code cycles, the wall-bracing provisions in the IRC have become increasingly complex. To help navigate these requirements and calculate the required bracing length for a given wall line, Simpson Strong-Tie introduced the Wall-Bracing-Length Calculator (WBLC) a few years back, as discussed in an earlier blog post. I’ll also mention that the WBLC has since been updated to the 2015 IRC.

Holdown Anchorage Solutions
A couple years ago, I did a post on selecting holdown anchorage solutions. At the time, we had created a couple engineering letters that tabulated SSTB, SB and PAB anchor solutions for each holdown to simplify specifying anchor bolts. About a year later, a salesperson suggested we tabulate SSTB, SB and PAB anchor solutions for each holdown. You know, to simplify specifying anchor bolts…
This conversation reminded me of the difficulty in keeping track of where design information is. In the C-C-2017 Wood Construction Connectors catalog, we have added this material on pages 62-63. Which should make it easier to find. I thought I should update this blog post to correct the links to this information.
A common question we get from specifiers is “What anchor do I use with each holdown?” Prior to the adoption of ACI 318 Appendix D (now Chapter 17 – Anchoring to Concrete), this was somewhat simple to do. We had a very small table in the holdown section of our catalog that listed which SSTB anchor worked with each holdown.
