The Canada Structural Engineers Association (CSEA) hosted the webinar on foundation design on June 12, 2021. More than 70 people participated in this webinar.
The first guest speaker Brady Lin introduced two case studies of deep foundation. The first one is for the driven pile. This case study demonstrated that when the Standard Penetration Testing failed to provide representative soil characteristics, how the pile load testing helped identify the problem and determined a resolution in the early stage. The second one is for a bridge located in Guelph, Ontario. He introduced the challenges, mitigations, and resolutions for east and west caissons. During the break between the two presentations, Liao Haixue introduced CSEA.
The second guest speaker Robin Chi introduced the steel pile application in bridge design. This type of foundation is mostly used in integral abutment, which is the major type of new bridge. The content includes comparing the steel piles and caissons, the related parts in MTO Structural Manual, and the integral abutment bridges with steel piles.
After the webinar, Slides and video recording were sent to the participants by CSEA staff. About the Speakers:
