Design of any building is a challenge for architects and engineers, and the challenge is made more complex when there is a need to provide for earthquake resistance.
During the past 100 years, seismic design philosophy and details have progressed from simply considering earthquakes to be the same as wind loads, to a sophisticated understanding of the phenomenon of the earthshaking that induces a building response.
This course covers the 100-year history of seismic structural systems, ranging from simple to sophisticated solutions. Basic structural behavior is outlined; guidance for selecting a good structural system is suggested, and relevant seismic issues are explored.

Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 10 questions. PDH credits are not awarded until the course is completed and quiz is passed.
This course teaches the following specific knowledge and skills:
- A summary of 100 years of structural seismic design
- Current and historical structural seismic systems, ranging from pre-1906 San Francisco earthquake to present day
- Three main factors that have impacted the progression of seismic systems selected by structural engineers
- The many variables that make it difficult to select an appropriate seismic system
- Why the simple building code approach to seismic design is often inadequate
- Why lateral drift that is too large or too small results in seismic performance issues
- “Pushover” performance comparisons of six different structural systems for a 4-story building
- Why energy dissipation is an important factor in a building’s overall seismic performance
- Energy dissipating concepts developed in 1976 at the New Zealand National Laboratory
- Seismic performance characteristics, including non-linear drift, energy dissipation and cyclic behavior, for twenty different structural systems
- Why building configuration is frequently the governing factor in the ultimate seismic behavior of a particular structure
