Dynamic, In-situ, Nonlinear-Inelastic Response and Post-Cyclic Strength of a Plastic Silt Deposit

by admin | Nov 29, 2022

This study presents the use of controlled blasting as a source of seismic energy to obtain the coupled, dynamic, linear-elastic to nonlinear-inelastic response of a plastic silt deposit. Characterization of blast-induced ground motions indicates that the shear strain...

Dynamic, In-situ, Nonlinear-Inelastic Response of a Deep, Medium Dense Sand Deposit

by admin | Nov 29, 2022

This study presents the use of controlled blasting for the determination of the in situ dynamic response of a sand deposit at a depth of 25 m under effective overburden stresses of approximately 250 kPa. The experiments were performed to establish the suitability of...

Deep, In-Situ Nonlinear Dynamic Testing of Soil with Controlled Blasting: Instrumentation, Calibration, and Application to a Plastic Silt Deposit

by admin | Nov 29, 2022

This study presents a novel test method to obtain dynamic properties of soil in situ using controlled blasting. Experimental and calibration protocols have been developed to conduct such investigations for any soil at any depth to obtain the coupled response between...

Monotonic, Cyclic, and Post-Cyclic Responses of an Alluvial Plastic Silt Deposit

by admin | Nov 29, 2022

This study presents a comprehensive investigation into the monotonic, cyclic, and postcyclic response of a medium stiff, plastic, lightly-overconsolidated, alluvial clayey silt deposit. The laboratory investigation is performed on natural, intact, and reconstituted...

Multihazard Damage and Loss Assessment of Bridges in a Highway Network Subjected to Earthquake and Tsunami Hazards

by admin | Nov 29, 2022

The objective of this study is to examine and compare the vulnerabilities of highway bridges to the combined effects of earthquake shaking, ground failure, and tsunami loading. Earthquake-induced ground shaking, ground failure (e.g., landslides and liquefaction), and...
