Research Impact

A research team led by Professor Kenichi Soga was recently granted $3 million by the California Energy Commission to enhance the seismic risk assessment of natural gas storage and pipeline infrastructure. Over three years, the team will use remote and embedded sensing technology and advanced data management and analysis techniques to monitor gas infrastructure continuously.

Abstract

Major advances in earthquake engineering have generally occurred because of significant earthquake events. Today marks the anniversary of two such events. At 4:31 am Pacific Time on January 17, 1994, the Northridge Earthquake, a magnitude 6.7 event, occurred in the San Fernando Valley with a duration of 10-20 seconds.

Funded by the National Science Foundation (NSF), the Converging Design project includes full-scale testing of a six-story mass timber building at the Natural Hazards Engineering Research Institute (NHERI) Large-High Performance Outdoor Shake Table. The project re-uses the bottom six stories of a 10-story mass timber building previously tested as part of the NSF Tallwood project.
