Fragility Functions for Liquefaction-Induced Ground Failure
Publisher: ASCE
Abstract: The predicted severity of liquefaction manifested at the ground surface is a popular and pragmatic proxy of damage potential for infrastructure. Toward this end, the liquefaction potential index (LPI) and similar models ...
Selecting the Optimal Factor of Safety or Probability of Liquefaction Triggering for Engineering Projects Based on Misprediction Costs
Publisher: ASCE
Abstract: In deterministic evaluations, liquefaction triggering potential is assessed by comparing the computed factor-of-safety (FS) against liquefaction triggering to some minimal acceptable FS. While some guidelines are available ...
Probabilistic Liquefaction Triggering and Manifestation Models Based on Cumulative Absolute Velocity
Publisher: ASCE
Abstract: This study proposes the capacity cumulative absolute velocity (CAVc) as a novel measure for the resistance of granular soils to earthquake-induced liquefaction. The CAVc is defined as the cumulative absolute velocity (CAV) ...
Limitations of Surface Liquefaction Manifestation Severity Index Models Used in Conjunction with Simplified Stress-Based Triggering Models
Publisher: ASCE
Abstract: The severity of surface manifestation of liquefaction is commonly used as a proxy for liquefaction damage potential. As a result, manifestation severity index (MSI) models are more commonly being used in conjunction with ...
True Liquefaction Triggering Curve
Publisher: American Society of Civil Engineers
Abstract: Current simplified models for predicting liquefaction triggering and manifestation do not account for the mechanisms of liquefaction triggering and surface manifestation in a consistent and sufficient manner. Specifically, ...
