Shallow Foundation Design with Liquefiable Soils
This presentation will go through Design Example 62 “Shallow Foundation Design with Liquefiable Soils”. The design example is based on an actual project in which an existing building on a site with liquefiable soils and with shallow foundations was required to be brought to current building code standards. It delves into ASCE 7-16 Section 12.13.9, discussing when shallow foundations can be used and for what parameters they must be designed on sites with liquefiable soils.
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.
