Abstract
Using the performance mode approach (which is referred as the failure mode approach in the literature), a system reliability evaluation procedure is proposed for pile-founded structures. Both strength and serviceability performance modes are considered. The individual pile behavior is considered to be brittle-type and the group behavior is considered to be parallel-type. Using the advanced first-order second-moment method, the element-level probability of unsatisfactory performance of a pile is calculated for the strength performance mode, and the system-level probability of unsatisfactory performance of the pile cap is calculated for the serviceability performance mode. A procedure to identify significant performance modes is proposed, and the bounds for the system probability of unsatisfactory performance are estimated. The procedure is explained with the help of an example. The proposed procedure significantly improves the state of the art in the evaluation of system reliability of pile-supported structures.
