This webinar includes discussion on the terminology and types of fill walls, lateral earth pressure theories for fill walls, permanent and transient surcharge loads, applicable load factors, use of minimum and maximum load factors for permanent loads, identification of limit states and resistance factors, pressure surfaces for geotechnical and structural analysis, and consideration of extreme event limit states such as seismic events. This part of the webinar series assumes that the participant has a basic working knowledge of design and construction of fill retaining walls including fundamental aspects of earth pressure theories.

The webinar on fill walls will concentrate on external stability of CIP and MSE walls. Introductory information on internal stability of MSE walls in the context of limit states and general concepts will also be presented. A separate webinar on MSE walls is available that addresses MSE walls in more detail.
