What is Shear Key Design in Retaining Walls about?
This document discusses factors of safety for retaining wall footings against overturning and sliding according to AASHTO standards. It provides the minimum acceptable safety factors for different load cases including static, seismic, and collision loads. It also discusses methods to increase resistance to sliding, such as adding shear keys or widening footings. Finally, it presents the Rankine formula for calculating passive soil resistance at shear keys, which provides lateral support for the wall.
