Shallow Foundation Design with Liquefiable Soils and Pile Foundations

Description

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.

Pile Foundations
Many of the questions regarding cold-formed steel framed seismic force-resisting systems regard the which floor framing system should be used, overturning restraint options and their design and detailing, wall stud bracing design and detailing, the use of the overstrength and expected strength factors, and the difference between previous to latest code design requirements. This presentation will focus on these aspects of design as covered in the SSDM design example.

Course will award 1.5 hours of continuing education
