Deterministic and probabilistic assessment of margins of safety for internal stability of as-built PET strap reinforced soil walls
The paper demonstrates deterministic and reliability-based assessment of strength limit
states (tensile resistance and pullout) and the service limit state for soil failure for
mechanically stabilized earth (MSE) walls constructed with polyester (PET) strap
reinforcement. The general approach considers the accuracy of the load and resistance
models that appear in each limit state equation plus uncertainty in the estimate of nominal
load and resistance values at time of design. Reliability index is computed using a closed …
