Abstract

Abstract: Some theoretical models have been developed over the years by the authors dealing with reliability-based design of geotechnical systems. A comparison reveals that these models follow the same form which can be used to develop a unified reliability-based model, which includes the effects of spatial variability, site understanding, and failure consequence severity. This paper describes the unified model and applies it to four geotechnical problems to determine resistance and consequence factors to be used in design. The problems considered are the ultimate and serviceability limit state design of shallow foundations and ultimate and serviceability limit state design of deep foundations.
