Abstract: This paper has two objectives. The first is to evaluate the cyclic shear strain needed to trigger liquefaction,

Abstract: This is the written version of the H. Bolton Seed Medal Award Lecture presented at the ASCE Geotechnical and Structural Engineering Congress in Phoenix, Arizona, February 14–17, 2016. It discusses five recent findings on ...

Abstract: The nonlinear response of shallow foundations when subjected to combined loading has attracted the attention of the research engineering community over the last few decades, providing promising evidence for incorporation ...

Abstract: The effect of extensive liquefaction on the liquefaction resistance of heavily preshaken saturated silty sand is studied using a centrifuge experiment. The base of a 6-m homogeneous deposit was subjected to a total of 91 ...

Abstract: Field observations suggest that preshaken natural sands in some seismic regions have high liquefaction resistance as a result of geologic aging and/or preshaking. This paper focuses on the young silty sand deposits located ...

Abstract: This article presents numerical simulations investigating pore pressure buildup of a sand layer with a free drainage boundary at the top under both low and high overburden pressures and subjected to earthquake base excitation. ...

Abstract: This paper studies the effect of a high effective overburden pressure [σv0′= ∼600 kPa (6 atm)] under two drainage conditions on the field liquefaction behavior of saturated Ottawa sand. A series of eight centrifuge ...
