Geotechnical Uncertainties and Reliability-Based Design
A rational approach to uncertainties in geotechnical design is reliability-based design (RBD) and a readily useable form is load resistance factor design (LRFD). In LRFD, load and resistance factors are used to obtain an acceptable level of reliability or failure probability. This paper reviews the development of reliability-based design and the various uncertainties that control the resistance factor. These include uncertainties about material models, analytical models, and methods for reliability assessment. Data available from various sources are compared. The estimated uncertainties are compared with observed performance from case histories and current design codes. Implications on use of LRFD in practice are suggested. Uncertainty about the load is not considered here because an extensive literature already exists.
