<p>For many years, engineers have designed foundations, walls and culverts for highway and other geotechnical applications using allowable stress design (ASD) methods. In ASD, all uncertainties in the load and resistance are combined into a global factor of ...

Significant research has been performed in recent years to develop load and resistance factor design (LRFD) methods for geotechnical applications. However, one lacking aspect of this work is application to design of earth slopes, including consideration of ...

The purpose of this Circular is to assist both structural and geotechnical engineers to better understand the calibration process and what information is required to perform such calibrations. The Circular describes how such calibration efforts need to be ...

The primary objective of this study is to propose a Limit States Design method for shallow and deep foundations that is based on a rational, probability-based investigation of design methods. In particular, Load and Resistance Factor Design is used to facilitate ...

This report contains the findings of a study to develop resistance factors for driven pile and drilled shaft foundations. These factors are recommended for inclusion in Section 10 of the AASHTO LRFD Bridge Design Specifications to reflect current best practice ...
