This recorded webinar is based upon the design examples “Pile Foundations & FEMA P-1051 Design of Piles for Lateral Spreading Design Examples” in Volume 3 of the SEAOC 2015 IBC Structural/Seismic Design Manual series.
The presentation includes a review of Example 5 of Volume 3, which pertains to the design of a cast-in-place concrete pile foundation. The foundation addressed in the example is a post-tensioned concrete parking garage. However, the pile design methodology is applicable to any building. The presentation includes recommendations for coordination with the geotechnical engineer, determination of the most cost-effective geotechnical pile capacity for the project, determining the number of piles at each location, geotechnical and structural design of the piles to resist vertical and lateral loading, distribution of base shear, review of applicable Code requirements and recommendations for detailing. The presentation will also include a brief design example addressing the ASCE7-16 design of piles to sustain lateral spreading.
Please note that continuing education credit is not available for recorded webinars.

Steve Harris has practiced structural engineering for over 30 years and is a principal at Simpson Gumpertz & Heger Inc. He is a graduate of the University of California at Davis and a registered Structural Engineer. His experience includes design of new structures, seismic strengthening of existing structures and design of pile foundation systems. His pile foundation designs include the 49ers Levi’s Stadium, Facebook’s new West Campus, Samsung’s new American Headquarters in San Jose, and the new SFO Control Tower. Other noteworthy projects include the seismic upgrade of the War Memorial Veterans Building in San Francisco, the expansion, remodel, and seismic upgrade of the J. Paul Leonard & Sutro Library at San Francisco State University, design of the 29-story 199 Fremont office building in San Francisco and the design of forty-two new Bachelor Enlisted Quarters buildings at USMC Base, Camp Pendleton, CA.
About the SEAOC 2015 IBC Structural/Seismic Design Manual (SSDM)
The SEAOC Structural/Seismic Design Manual (SSDM), throughout its many editions, has served the purpose of illustrating good seismic design and the correct application of building-code provisions. The SSDM has bridged the gap between the treatment of topics in the building code and ASCE 7, the SEAOC Blue Book (Recommended Lateral Force Requirements and Commentary) and real-world decisions that designers face in their practice.
The SSDM uses example buildings to illustrate code-compliant designs engineered to achieve good performance under seismic loading. The examples address the full range of seismic design considerations, from conceptual level through details of connections and load path. In some cases simply complying with building-code requirements does not ensure good seismic response; here the SSSDM makes recommendations for exceeding the minimum code requirements in such cases, with discussion of the reasons for doing so.
The newly released 2015 SEAOC SSDM has updated and revised the examples for consistency with the 2015 edition of the International Building Code. Volumes 1, 2, and, 3 (addressing light-frame, tilt-up, masonry, and reinforced concrete buildings) have had the most significant changes. Learn more and purchase your copies today >
