In this episode of The Structural Engineering Channel podcast, we will be taking to Ronald O. Hamburger, SE who is a Senior Principal at Simpson Gumpertz & Heger and Evan Reis, SE, co-founder of the U.S. Resiliency Council. We will be talking about recent articles in the New York Times on the concept of base isolation, including the article: Buildings Can Be Designed to Withstand Earthquakes – Why Doesn’t the U.S. Build More of them?

Here Are Some of the Questions We Ask Our Guests in This Episode:
- What are the reasons behind the big difference between the number of buildings in the US and other countries that utilize base isolation?
- Has base isolation been in the code for a while already?
- Do you think there is really a need for base isolation in the U.S.?
- Tell us about the U.S. Resiliency Council and what the mission of the council is?
- What is your opinion on some of our existing buildings that are not safe?
Here Are Some of the Key Points Discussed About Base Isolation:
- Base isolation is a technique developed to prevent or minimize damage to buildings during an earthquake.
- The reasons behind the big difference in buildings in our countries are largely due to economical reasons as opposed to technical reasons. While it is not much more expensive to build a base-isolated building in the U.S. than it is in other countries, there are some incremental construction costs associated with base isolation, which is the primary reason that it’s not being used for many structures in the U.S.
- I think the most exciting thing about structural engineering is the proliferation of a design technology that is called performance-based design, which provides flexibility to engineers during designs.
- The better our buildings can perform when hit by natural disasters, the more sustainable they will become.
- The U.S. Resiliency Council was founded as a way to use engineering technology that was developed by organizations like The American Society Of Civil Engineers , FEMA, and others to quantify the performance of buildings in earthquakes and other natural disasters.
- One of the key reasons why we don’t see anywhere near the same number of base isolated buildings in the US as we do in other countries is because there is a perceived low probability of a disaster occurring in an area.
- We have the opportunity to see what resilience is and what the structural engineering profession means. Not just for a building, but for the entire community which that building serves. The engineering profession as a whole should take advantage of this opportunity and promote the value that engineers provide.
