RISFragility 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 ...
A Pragmatic Framework for Cost-Benefit Analysis of Liquefaction Mitigation Applicable to Lightweight Residential Structures on Shallow Foundations
Publisher: American Society of Civil Engineers
Abstract: Liquefaction hazards are often not assessed or mitigated for lightweight residences on shallow foundations despite their comprising 90% of the US building stock. This study demonstrates a pragmatic approach to performing ...
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, ...
