The modern concept of seismic base isolation revolutionized seismic protection of structures and their functions.  From the time of the earliest U.S. applications of seismic isolation in the mid-1980’s, structural engineers have continued to innovate and invent effective ways to apply this promising concept to both new and existing buildings, bridges, and other important structures and systems.  This presentation seeks to illustrate the evolution of application of seismic isolation in structural engineering practice, and to highlight some of the significant technical challenges encountered - and creative solutions developed - in implementing this promising technology. 


Mason Walters Headshot
Mason Walters is a Senior Principal at Forell/Elsesser and has been with the firm since 1984.  Mason has had 40 years of experience in structural analysis and design of buildings, long-span bridges, and other structures.  Mason’s career includes pioneering applications of seismic isolation and energy dissipation for new and historic structures, seismic design of reinforced and post-tensioned concrete and steel building and bridge structures.  Several of Mason’s projects have gained special recognition for their unique structural solutions. Mason is registered as a structural engineer in eight states and is a member of the Seismic Advisory Boards of both University of California and Caltrans.  In 2019 Mason was awarded the H.J. Brunnier Lifetime Achievement Award by the Structural Engineers Association of Northern California for outstanding achievement in structural engineering.
