Ocean Bottom Hydrodynamic Pressure due to Vertical Seismic Motion
Publisher: ASCE
Abstract: Earthquake-induced hydrodynamic pressure on the ocean floor is a key factor in evaluating the surface disturbance and dynamic response of the seabed under the action of a submarine earthquake. An analytical study considering ...
Liquefaction Susceptibility of Saturated Coral Sand Subjected to Various Patterns of Principal Stress Rotation
Publisher: ASCE
Abstract: The influences of consolidation conditions and rotation patterns of principal stress on the liquefaction susceptibility of saturated coral sand have emerged as an interesting problem in recent years. This paper presents ...
Excess Pore-Water Pressure Generation in Cyclic Undrained Testing
Publisher: American Society of Civil Engineers
Abstract: A new strain-based model is presented in this paper for assessing the residual excess pore-water pressure (ue) buildup in fully saturated sands. In this model, the generation of residual ue is quantified by the volumetric ...
A Unified Formula for Small-Strain Shear Modulus of Sandy Soils Based on Extreme Void Ratios
Publisher: American Society of Civil Engineers
Abstract: Small-strain shear modulus (G0) is a fundamental property required in dynamic analyses. For sandy soils, G0 may be affected strongly by particle characteristics such as uniformity coefficient (Cu), mean particle size (d50), ...
A Unified Model of Cyclic Shear–Volume Coupling and Excess Pore Water Pressure Generation for Sandy Soils under Various Cyclic Loading Patterns
Publisher: American Society of Civil Engineers
Abstract: Accurate prediction of excess pore water pressure (EPWP) generation in saturated sandy soils remains one of the most challenging issues in sandy site responses to strong earthquakes and extreme marine environments. This ...
A Binary Packing Material–Based Procedure for Evaluating Soil Liquefaction Triggering during Earthquakes
Publisher: ASCE
Abstract: This paper presents a new approach to assess the liquefaction triggering of saturated sandy soils based on comprehensive laboratory datasets in conjunction with the concept of binary packing material for sandy soils. The ...
