RISConsiderations for the Mitigation of Earthquake-Induced Soil Liquefaction in Urban Environments
Publisher: American Society of Civil Engineers
Abstract: In cities, seismic coupling between structures is known to influence ground motions, settlement patterns, and demand on superstructures. Yet the effects of interactions between soil and building clusters on structural ...
Influence of Dense Granular Columns on the Performance of Level and Gently Sloping Liquefiable Sites
Publisher: American Society of Civil Engineers
Abstract: Dense granular columns are often used as a liquefaction mitigation measure to (1) enhance drainage; (2) provide shear reinforcement; and (3) densify and increase lateral stresses in the surrounding soil ...
Influence of Prefabricated Vertical Drains on the Seismic Performance of Structures Founded on Liquefiable Soils
Publisher: American Society of Civil Engineers
Abstract: Prefabricated vertical drains (PVDs) are commonly used to mitigate the liquefaction hazard and its consequences. However, the influence of enhanced drainage on the response and performance of soil, foundation, and structure ...
Machine Learning–Based Settlement Models for Shallow-Founded Structures on Interbedded Liquefiable Sites Considering Dense Granular Columns
Publisher: American Society of Civil Engineers
Abstract: AbstractIn this paper, we introduce physics-informed, machine learning (ML)–based predictive
models for the permanent settlement of foundations on stratigraphically variable liquefiable
deposits. In this paper, we define ...
Site Response in a Layered Liquefiable Deposit: Evaluation of Different Numerical Tools and Methodologies with Centrifuge Experimental Results
Publisher: American Society of Civil Engineers
Abstract: Results of a centrifuge experiment simulating seismic site response in a layered level liquefiable soil profile are used to evaluate and systematically compare the predictive capabilities of two common numerical platforms ...
A Machine Learning–Based Predictive Model for Liquefaction Ejecta Manifestation in Stratigraphically Variable Sites
Publisher: American Society of Civil Engineers
Abstract: AbstractThis paper presents a machine learning–based probabilistic predictive model for estimating
the potential severity of free-field surface ejecta in stratigraphically variable
and interbedded deposits as a measure of ...
Influence of Tall Buildings on Seismic Response of Shallow Underground Structures
Publisher: American Society of Civil Engineers
Abstract: Shallow underground structures are commonly built in close proximity to tall buildings in dense urban environments. Although it is well known that such buildings have the potential to affect ground motions in their vicinity ...
