The Legacy of Loma Prieta

Every year on October 17, we take a moment to reflect on the 1989 Loma Prieta earthquake. The 6.9-magnitude earthquake was one of the most powerful and costly quakes to shake the San Francisco Bay area since the 7.9-magnitude earthquake of 1906. The quake caused an estimated $6 billion in damage and, tragically, resulted in 63 deaths and 3,757 injuries.

Many of those casualties were due to failing infrastructure when sections of the Nimitz Freeway collapsed.

Simpson Strong-Tie was founded in Oakland, California — practically in the heart of the Bay Area. Earthquakes were never far from the minds of our founders. It’s why even before Loma Prieta our mission was to provide solutions that help people design and build safer, stronger structures. However, it’s safe to say the earthquake not only reinvigorated our mission but inspired countless structural engineers who would go on to define the next 30 years of Simpson Strong-Tie research and development into community resilience.

Case Study: Gruening Middle School’s Seismic Damage Repair Solution

It can be a challenge to repair an earthquake-damaged structure.

During the 7.1-magnitude 2018 Anchorage earthquake, Gruening Middle School in Eagle River sustained more damage than any other school in the Anchorage School District. Review of the school showed the existing masonry walls suffered damage and separation from the roof. During the retrofit design, the Reid Middleton structural engineering team (Anchorage) determined the masonry walls weren’t adequately reinforced to meet current code requirements. They were seeking an easy-to-install strengthening solution that wouldn’t add significant weight to the building.

Build Change: My Favorite Child

With the growing danger of natural disasters, the race is on to expand access to programs that safeguard lives from the human-made danger of poorly built housing. With the common mission of building safer, stronger structures, Build Change and Simpson Strong-Tie have partnered for the Simpson Strong-Tie® Fellowship for Engineering Excellence program. This year’s fellow is Build Change Engineering & Design Services Director Tim Hart, SE. As with our previous fellows, Hart is documenting his journey with the program on the Simpson Strong-Tie Structural Engineering blog. This is his final report.

In 2017, when I was in Nepal working for Build Change, I had a conversation with one of my colleagues about the volunteer work that I had done for the organization over the years. After telling him that I had worked with seven different country programs for Build Change, he asked me which of those countries I liked the best. My first thought was that it was like asking a parent which child he or she liked the best; even if I did have a favorite, I didn’t want to say it out loud for fear of offending my colleagues and friends in all the other countries. I said this to him to deflect the conversation and we went on to discuss other topics. Truth be told, while I enjoyed the culture and hospitality of all my Build Change host countries and believe in the value of the work I’ve done for them , I have a special soft spot for two of them: Indonesia and Nepal.

Business Owners Today: What Else Could Happen?

How can a “Back-to-Business” plan help communities and business owners recover after a damaging event? In this guest blog post, David Cocke, S.E., explores the history of “B2B” programs and how they help expedite the inspection process so owners can get back to normal faster.

Business leaders have a lot to think about nowadays. With the current pandemic crisis, we have to consider health (ourselves, our families and our staff), liabilities, cash flow, workload, client retention and the pipeline for future work. Knock on wood that we don’t have to deal with any kind of natural disaster on top of this current situation, but more on that topic later…

Build Change: Seismic Safety in the Age of COVID-19

With the growing danger of natural disasters, the race is on to expand access to programs that safeguard lives from the human-made danger of poorly built housing. With the common mission of building safer, stronger structures, Build Change and Simpson Strong-Tie have partnered for the Simpson Strong-Tie® Fellowship for Engineering Excellence program. This year’s fellow is Build Change Engineering & Design Services Director Tim Hart, SE. As with our previous fellows, Hart is documenting his journey with the program on the Simpson Strong-Tie Structural Engineering blog.

When I agreed to travel for Build Change to the Philippines and Indonesia in March, some of my friends and colleagues told me I was brave. Others told me I was crazy. One asked me whether I was afraid that I would not be able to get home. At the time, I felt it was safe to go since there were only a few cases reported in the Philippines, Indonesia and the United States. Even so, I waited until the last minute before I told my mother of the trip, knowing that she would be worried and would try to talk me out of going.

Dr. Lucy Jones: Mitigation Creates Community Resilience

A Shinto shrine in the Japanese coastal town of Minamisanriku has been the center of its community for centuries. In 1960, a tsunami generated by the great Chilean M9.5 earthquake swept into the ocean bay and damaged the shrine. The priest’s house situated at a higher elevation than the shrine had been spared any damage. The community came together and not only repaired the shrine but moved it up the hill, 50 feet above its previous location, to protect it from future events.

The Simpson Strong-Tie Excellence in Engineering Fellowship, A Grateful Adventure

Before starting my fellowship, a year seemed like a very long time to be away from my day-to-day life, my clients, and my comfort zone. I started with many questions about how I could support the Build Change team to make the biggest possible impact with this fellowship. Once I started, however, I found more than a great team; I found a family. I would like to start this blog by praising the support of every member of the teams that I worked with, including the Build Change headquarters staff, as well as the staffs of the programs in Colombia and the Philippines.

Designing Resilience: NEESWood Capstone a Decade Later

In 2009, Simpson Strong-Tie participated in an unprecedented research event to highlight the importance of earthquake-resistant wood construction.

The event, the world’s largest earthquake test, was a collaborative Network for Earthquake Engineering Simulation project. It teamed academics, engineers, and industry researchers from around the world to subject a structure to what engineers refer to as the “maximum considered event” (MCE), a large, rare earthquake projected to occur, on average, approximately every 2500 years.

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.

5 Steps to a Successful Soft-Story Retrofit

Last year, I gave a presentation at the annual National Council of Structural Engineers Associations (NCSEA) Summit in Orlando, Florida, titled “Becoming a Trusted Advisor: Communication and Selling Skills for Structural Engineers.” As this was a summit for the leaders of the structural engineers associations from across the country, I wasn’t sure how many people would find it valuable to spend their time learning about a very nontechnical topic. To my surprise and delight, the seminar ended up being standing-room only, and I was able to field some great questions from the audience about how they could improve their selling and communication skills. In the many conversations I had with the conference attendees after my presentation, the common theme was that engineers felt they needed more soft-skills training in order to better serve their clients. The problem, however, was finding the time to do so when faced with the daily grind of design work.

Structural Engineers In a Training for Seismic Retrofits
Presenting at the NCSEA Summit, I’m the tiny person in upper left hand corner.

When I started my first job as a design engineer at a structural engineering consulting firm straight out of school, I was very focused on improving and expanding my technical expertise. Whenever possible, I would attend building-code seminars, design reviews and new product solution presentations, all in an effort to learn more about structural engineering. What I found as I progressed through my career, however, was that no matter how much I learned or how hardworking I was, it didn’t really matter if I couldn’t successfully convey my knowledge or ideas to the person who really mattered most: the client.

How can an engineer be most effective in explaining a proposed action or solution to a client? You have to be able to effectively sell your idea by understanding the needs of your client as well as any reasons for hesitation. The importance of effective communication and persuasion is probably intuitive to anyone who’s been on the sales side of the business, but not something that occurs naturally to data-driven folks like engineers. As a result of recent legislation in California, however, structural engineers are starting to be inundated with questions from a group of folks who have suddenly found themselves responsible for seismically upgrading their properties: apartment building owners in San Francisco and Los Angeles.

Imagine for a moment that you are a building owner who has received a soft-story retrofit notice under the City of Los Angeles’ Ordinance 183893; you have zero knowledge of structural engineering or what this term “soft-story” even means. Who will be your trusted advisor to help you sort it out? The City of Los Angeles Department of Building and Safety (LADBS) has put together a helpful mandatory ordinance website that explains the programs and also offers an FAQ for building owners that lets them know the first step in the process: hire an engineer or architect licensed in the state of California to evaluate the building.

I’ve had the opportunity to be the first point of contact for a building owner after they received a mandatory notice, because it turns out some relatives own an apartment building with soft-story tuck-under parking. Panicked by the notice, they called me looking to understand why they were being forced to retrofit a building that “never had any problems in the past.” They were worried they would lose rent money due to tenants needing to relocate, worried about how to meet the requirements of the ordinance and, most importantly, worried about how much it was going to cost them. What they really wanted was a simple, straightforward answer to their questions, and I did my best to explain the necessity behind retrofitting these vulnerable buildings and give an estimated time frame and cost that I had learned from attending the first Los Angeles Retrofit Resource Fair in April 2016. With close to 18,000 buildings in the cities of San Francisco and Los Angeles alone that have been classified as “soft-story,” this equates to quite a number of building owners who will have similar questions and be searching for answers.

To help provide an additional resource, Simpson Strong-Tie will be hosting a webinar for building owners in the Los Angeles area who have received a mandatory soft-story retrofit notice. Jeff Ellis and I will be covering “5 Steps to a Successful Retrofit” and helping to set a clear project path for building owners. The five steps that Simpson Strong-Tie will be recommending are:

  1. Understanding the Seismic Retrofit Mandate
  2. Partnering with Design Professionals
  3. Submitting Building Plans with the Right Retrofit Product Solutions
  4. Communicating with Your Building Tenants
  5. Completing Your Soft-Story Retrofit

We encourage you to invite any clients or potential clients to attend this informative webinar, which will lay the foundation for great communication between the two of you. As part of the webinar, we will be asking the building owners for their comments, questions and feedback so we can better understand what information they need to make informed decisions, and we will be sure to share these with the structural engineering community in a future post. By working together to support better communication and understanding among all stakeholders in retrofit projects, we will be well on our way to creating stronger and more resilient communities!
