California and earthquakes

Are we prepared for an earthquake?

Geoff Warcholik

As the world continues to watch, monitor and respond to Japan’s terrible earthquake, tsunami and resulting damage, we in California are reminded once again that we, too, reside in the “Ring of Fire” – along the Pacific Rim that experiences the most earthquakes in the world. Californians can expect a serious earthquake to hit here, too. Scientists at the University of California at Irvine have recently updated their predictions. They now say a major quake on the San Andreas fault is not only imminent, it’s long overdue.

We, the members of Structural Engineers Association of California, continue to research, investigate and design better ways to build homes, schools, bridges, hospitals, dams and other infrastructure to keep our communities functioning in a disaster. We have the technology. We have the resources. We have the trained professionals to do the job.

But now we need government to join forces with us to secure the safety of our populations and cities. Together we should consider developing more stringent building codes, and enforcement policies for our hospitals, schools, commercial buildings and residences. What’s more, government should offer incentives to commercial and residential building owners to encourage them to retrofit old buildings and build better structures. Officials might even need to consider penalizing building owners who don’t comply.

Lastly, our elected officials must assure all municipal buildings and emergency service facilities – our schools, fire and police stations and state-run hospitals – are all built and retrofitted to avoid failure during an earthquake.

Japan’s officials have set a good example for us and other countries to follow. They have stringent building codes. They have regular emergency preparedness drills for their citizens. And they have assured that almost 100 percent of their medical facilities have remained operational following their recent horrific events.

Are we as prepared in San Diego or California? The answer is, “Not entirely.” While we do have better building codes than most countries, our codes focus on preventing collapse of structures, not preventing damage, which is the goal of standards in Japan.

Take our housing stock, for example. In San Diego, we urge but do not mandate that homeowners take even the most basic steps of bolting their foundations, securing their gas water heaters and making sure other nonstructural components are secured. Fortunately for us, 85 percent of buildings in San Diego are one- and two-story wood-frame buildings which generally perform well in earthquakes. But this is only if they are bolted to their foundations and owners take seriously the task of securing heavy furniture, gas heaters and other internal structures that could topple and cause injury or fire.

At the same time, there are many old buildings in San Diego that are susceptible to heavy damage or collapse. The city has required building owners to partially retrofit these structures but they need financial help to do a more complete job. We recommend that the city consider a system of credits similar to what is used to encourage solar energy to help owners upgrade their properties.

What about our schools?

Fortunately, all new construction and additions to schools in San Diego, including K-12 and community colleges, have been designed to enhanced standards. But we should prod officials to review all older school buildings so that they also meet current standards. This is doubly important not only to protect our children but also because schools will be gathering sites for communities after any major seismic event.

Then there’s the question of our hospitals. To make sure that our hospitals would be ready in time for the next major earthquake, California legislators have demanded that by 2013 all hospital buildings serving patients that are deemed hazardous be replaced by new structures or retrofitted to a higher seismic safety standard. Here in San Diego, Palomar Pomerado Hospital actually was designed with the most current technology in mind even before the state adopted the code based on that technology.

In the past 16 years Californians have fixed many of the state’s weakest hospitals and built new ones. But, lately, the process has bogged down and proposals are not getting approved. We must make a new push to assure all of our medical facilities will be ready to meet the needs of the 36 million Californians following the next quake.

Our thoughts and prayers go out to those who lost their loved ones, their livelihoods and their homes in Japan’s catastrophic earthquake. And we shudder to think what might have happened if Japan did not already have some of the world’s most stringent standards of earthquake readiness.

How Earthquake-resistant Buildings Work

BY WILLIAM HARRIS

The Future of Earthquake-resistant Construction

The goal of earthquake-resistant buildings is to preserve life. That means a building that doesn't collapse and allows its inhabitants to escape is considered a success -- even if it ends up being demolished. But what if a building could experience deformation during a quake, then return to its original shape? For some researchers, such as Greg Deierlein of Stanford University and Jerome Hajjar of Northeastern University, that's the future of seismic engineering.

Deierlein and Hajjar have teamed up to develop an innovative technology known as the rocking frame, which consists of three basic components -- steel frames, steel cables and steel fuses. Here's how it works: When an earthquake strikes, the steel frames rock up and down to their heart's content. All of the energy gets directed downward to a fitting that houses several toothlike fuses. The teeth of the fuses gnash together and may even fail, but the frame itself remains intact. Once the shaking has stopped, the steel cables in the frame pull the building back into an upright position. Workers then inspect the fuses and replace any that are damaged. The result is a building that can be reoccupied quickly after an earthquake.

Another innovation is something that's been dubbed the seismic invisibility cloak, suggesting a building could be made transparent to the surface waves produced by an earthquake. To accomplish this, engineers would bury a series of up to 100 concentric plastic rings beneath the foundation of a building. When waves encounter the rings, they enter and then become compressed as they are forced into a bottleneck. The waves basically zip by, just beneath the building's foundation, and exit the rings on the other side, where they resume their original speed and amplitude.

Interestingly, much of the future of seismic engineering involves looking back, not forward. That's because retrofitting old buildings with improved designs and materials is just as important as constructing new buildings from scratch. Engineers have found that adding base-isolation systems to structures is both feasible and economically attractive. According to the National Earthquake Hazards Reduction Program, more than 200 buildings in the United States, including many city government and fire and emergency buildings, now feature isolation systems. After the 1989 Loma Prieta quake alone, engineers retrofitted several buildings, including the city halls of San Francisco, Oakland and Los Angeles. The earthquake-resistant structures in these buildings will most certainly face a test in the form of a serious seismic event. The only question is when and to what extent.
