Geotechnical reliability-based designs and links with LFRD

International Conference on Applications of Statistics and Probability (12th : 2015 : Vancouver, B.C.)

Reliability-based design (RBD) can play a useful complementary role to overcome some limitations in the Load and Resistance Factor Design (LRFD) approach, for example in situations where loads contribute not only destabilizing but also stabilizing effects, situations where load and resistance sensitivities vary due to different geometric and other details, situations with modeling of spatial variability and parametric correlations, and situations with different targets of probability of failure. Examples of reliability-based design and analysis are presented to show that under the above circumstances RBD can offer interesting and enlightening insights apart from suggesting back-calculated load and resistance factors. When statistical information is available, direct FORM analysis can also be performed on the design resulting from LRFD, to obtain estimated probability of failure. Illustrative examples of FORM RBD and FORM analysis in this study consist of a shallow footing design, an anchored sheet pile wall design, a laterally loaded pile with depth dependent nonlinear p-y curves, and a clay slope with anisotropic and spatially autocorrelated undrained shear strength.
