Seismic Engineering


"Assessing the seismic performance of buildings requires more than just the application of building codes. It requires an understanding of structural behavior at a local and global level. We apply the lessons learned in past earthquakes to improve our ability to recognize factors that affect seismic performance."

— Brian Kehoe, Associate Principal

Effective seismic evaluation and design require a practical understanding of earthquake motions and structure response. Having investigated the performance of structures during numerous earthquakes around the world, our engineers have an in-depth understanding of the seismic behavior of a wide range of structures as well as experience with performance-based designs that achieve the desired seismic response.

As leaders in the study of earthquake engineering, our experts have participated in the development of many of the earthquake engineering evaluation and analysis approaches currently in use and are regularly engaged to provide training on various aspects of seismic evaluation and design. Our strengthening designs have won numerous awards—particularly in the field of historic preservation—and our professionals are experts in seismic performance evaluations that go beyond standard practices and building code requirements.

Our expertise in seismic engineering and materials science is supported by substantial research and testing capability. Our cutting-edge, in-house laboratory facilities can accommodate virtually any construction-related research project, from evaluating the performance of full-size building elements to fatigue and fracture testing of individual structural components. Our solutions contribute to safer structures, limited earthquake damage, and allow clients to quickly return their structures to regular service.
