Probabilistic Seismic Hazard Analysis for the Sliding Displacement of Flexible Sliding Masses

The seismic performance of a slope that has a deeper critical sliding surface is quantified by the sliding displacement of a flexible sliding block. This project includes a Jupyter notebook that implements the Rathje et al. (2014) probabilistic approach to compute a hazard curve for the expected sliding displacement of a flexible sliding mass. This notebook requires as input the yield acceleration (ky) and natural site period (Ts) of the critical sliding mass, as well as the ground motion hazard in terms of the peak ground acceleration (PGA) hazard curve and the associated magnitude and distance de-aggregations. This Jupyter notebook interfaces directly with the U.S. Geological Survey Unified Hazard Tool such that the required ground motion hazard information can be input directly from the USGS website. The epistemic uncertainties in ky and Ts are captured through a user specified logic tree. References: Rathje, E. M., Wang, Y., Stafford, P. J., Antonakos, G., & Saygili, G. (2014).
