Earthquake expert whose research enhanced public safety dies at 85

Wilfred D. "Bill" Iwan, an ASCE Distinguished Member who was an innovator in engineering seismology and professor emeritus of civil engineering at California Institute of Technology, has died. He was 85.

Simple retrofit may keep the lights on after an earthquake

Brittle power transformer bushings tend to fail during large earthquakes, but researchers have found a way to reduce downtime and repair costs through a simple, inexpensive fix.

Preparing for inundation

Tsunamis might be infrequent and localized, but their impact on coastlines can be catastrophic. Find out how engineers’ long-running efforts to better protect coastal communities have finally paid off.

Flexible ‘cloaking’ material developed

A team of researchers led by Guoliang Huang, Ph.D., has designed a flexible “cloaking” material that has the potential to help buildings withstand vibrations, such as those created by seismic waves. The newly developed material is a multilayered, elastic lattice that can be stretched and formed to any surface and applied as a wrap, according to Huang, the James C. Dowell Professor in the University...

Learning about loss

Civil Engineers have learned a great deal from the catastrophic tsunami that struck Indonesia, India, Thailand, and Sri Lanka in December 2004.

New math model based on landslides and pinball analogy used to predict earthquake damage

A NEW MATHEMATICAL model uses a landslide model and a pinball machine analogy to help predict the damage caused by ground motions during seismic events. The new model was developed by Victor C. Tsai, Ph.D., an associate professor of geophysics in the Department of Earth, Environmental, and Planetary Sciences at Brown University, and Greg Hirth, Ph.D., a professor of geophysics in the same department at...

COVID-19 Community Calls 24: City of Dreams Part 2

Every day in April, ASCE Plot Points is calling a different civil engineer from around the world to find out how the COVID-19 pandemic is affecting their life, their community, their work and the civil engineering profession. Thirty days. Thirty phone calls. Community Call 24 continues our City of Dreams mini-series, talking to three young civil engineers working in Los Angeles. Jeena Jayamon is a project...

Salesforce Tower Named as OCEA Honor Award Recipient

Salesforce Tower, in San Francisco, has been honored by ASCE as a 2020 Outstanding Civil Engineering Achievement Honor Award recipient. All 10 Honor Award projects will be showcased at ASCE’s 2020 OPAL Gala, March 13, in Washington, D.C., with two runners-up and the OCEA winner announced at the event. Salesforce Tower is the tallest office building in a severe seismic zone in the Western Hemisphere. Standing...

Alaskan Way Viaduct Replacement Named OCEA Honor Award Recipient

The new State Route 99 tunnel in Seattle is the largest, machine-bored double-deck highway corridor in the world. Tens of thousands of vehicles now drive the two-mile-long tunnel each day and pass safely under streets, bridges, utilities and 157 buildings of all sizes. Making this tunnel required an industry heavyweight. “Bertha” was 57.5 feet wide and weighed more than 8,000 tons. She was anything but...
