RISSeismic Performance of Shallow Founded Structures on Liquefiable Ground: Validation of Numerical Simulations Using Centrifuge Experiments
Publisher: American Society of Civil Engineers
Abstract: The results of fully coupled, three-dimensional (3D), nonlinear finite-element analyses of structures founded on liquefiable soils are compared with centrifuge experiments. The goal is to provide insight into the numerical ...
Numerical and Centrifuge Modeling of Seismic Soil–Foundation–Structure Interaction on Liquefiable Ground
Publisher: American Society of Civil Engineers
Abstract: The effective mitigation of the liquefaction hazard requires an improved understanding of the consequences of liquefaction in terms of ground shaking, permanent displacement, and building performance. In this paper, results ...

Seismic Interactions among Multiple Structures Founded on Liquefiable Soils in a City Block
Publisher: ASCE
Abstract: Buildings are often located in close proximity to each other in urban settings. Seismic structure-soil-structure interaction near two adjacent buildings (SSSI2) on liquefiable soils has previously been investigated and ...
Impact of Spatial Variations in Permeability of Liquefiable Deposits on Seismic Performance of Structures and Effectiveness of Drains
Publisher: American Society of Civil Engineers
Abstract: Sand deposits are often stratified with thin layers of low-permeability silt. Previous studies have shown that the presence of sharp variations in permeability could slow down the dissipation of earthquake-induced excess ...
In-Ground Gravel–Rubber Panel Walls to Mitigate and Base Isolate Shallow-Founded Structures on Liquefiable Ground
Publisher: ASCE
Abstract: The effectiveness of a new liquefaction mitigation strategy is investigated experimentally for newly constructed shallow-founded structures: an in-ground gravel–rubber (GR) panel wall system. The goal was to limit the ...
Performance of Embankments on Liquefiable Soils Improved with Dense Granular Columns: Observations from Case Histories and Centrifuge Experiments
Publisher: ASCE
Abstract: Dense granular columns (DGCs) are generally known to mitigate the liquefaction hazard through a combination of (1) installation-induced ground densification, (2) enhanced drainage, and (3) shear reinforcement. ...
Probabilistic Predictive Model for Liquefaction Triggering in Layered Sites Improved with Dense Granular Columns
Publisher: ASCE
Abstract: This paper presents a probabilistic model for evaluating the liquefaction-triggering hazard in level, layered, and saturated granular soil profiles improved with dense granular columns (DGCs). The model is developed using ...
Impact of Ground Densification on the Response of Urban Liquefiable Sites and Structures
Publisher: ASCE
Abstract: Ground densification is a common countermeasure against soil liquefaction. The state-of-practice for designing ground densification is typically based on empirical estimates of liquefaction triggering and ground settlement ...
