C.B. Crouse

Bruce Bolt Medal | 2022 Recipient

C.B. Crouse has been a consultant in earthquake engineering and engineering seismology for 47 years. He works as principal engineer at AECOM in Seattle, Washington, where he primarily conducts seismic hazard and soil-structure interaction studies and develops earthquake ground motions (response spectra and time histories) for various types of projects throughout the world.

Crouse received his Ph.D. degree in civil engineering from Caltech. He was one of the early researchers to collect and use strong motion data to develop ground motion models (GMMs) for shallow crustal and subduction zone earthquakes. Since 2000, Crouse has chaired the ground motion and foundation design subcommittees for the National Earthquake Hazards Reduction Program (NEHRP) and American Society for Civil Engineers (ASCE) 7 seismic provisions. He is a former COSMOS and EERI board member and former associate editor of the Bulletin of the Seismological Society of America. Crouse has authored or coauthored some 75 earthquake engineering publications.

As chairman of the Southern California Earthquake Center (SCEC) Utilization of Ground Motion Simulations committee, he led the development of a web-based tool for obtaining site-specific MCER response spectra for Southern California per the requirements in Chapter 21 of ASCE 7-16. The approach used both the NGA West2 GMMs and 3D physics-based numerical simulations of ground motions from CyberShake.
