Upcoming Events

Using a collaborative and interactive learning approach, this 2-day virtual workshop will help you understand: (a) principles of lateral analysis of deep foundations, and (b) the types and effects of induced ground deformations on deep foundations. The workshop will help you assimilate the crucial considerations regarding these topics through active participation by frequent interactions throughout the workshop and real-time expert feedback. The interactions will facilitate a better understanding of the nuances of the various design procedures for deep foundations which would help you avoid costly design errors in real-world projects. In between the two live sessions, attendees will independently work on an application (e.g., exercises) or a reflection (e.g., reading) assignment.

Foundations for bridges and approach structures should be designed so that their movements will not damage the bridge superstructure and associated structures such as abutments and approach slabs. Various aspects of movements that should be considered in the design of bridges include (a) the effect of uneven (differential) settlement between various support elements, (b) the rotation and horizontal movements of the foundation system affecting movements at the bridge-seat level; (c) movements due to material deterioration; and (d) serviceability problems near a bridge abutment and approaches. The presentation will be based on latest (2020) version of the Bridge Design Specifications (BDS) and the Load and Resistance Factor Design (LRFD) platform of the American Association of State Highway and Transportation Officials which is a key component of Federal Highway Administration (FHWA) guidelines for this topic. Information on Extended Service Life (ESL) and Protection Index (PI) concepts from AASHTO’s latest (2020) Guide Specification for Service life design will also be presented.
