Abstract: A three-dimensional (3D) incremental plasticity constitutive model is developed for simulating the strain softening behavior of soil materials. The constitutive model extends an existing multiyield surface (MYS) plasticity ...

Abstract: Passive earth pressure is recorded in two different tests, using a 6.7-m long, 2.9-m wide soil container. In these tests, sand with 7% silt content is densely compacted behind a moveable test wall to a supported height of ...

Abstract: The three‐dimensional response of La Villita, an earth and rock‐fill dam in Mexico, during the earthquakes of November 15, 1975 and September 19, 1985, is investigated. A simplified numerical procedure is derived to represent ...

Abstract: Permeability of a liquefiable soil profile may affect the rate of pore-pressure buildup and subsequent dissipation during and after earthquake excitation. Consequently, effective soil confinement and available resistance ...

Abstract: The surface and downhole accelerations, and pore‐water pressures recorded during the 1987 earthquakes at a site in the Imperial Wildlife Management Area (Imperial County, Calif.) are used to obtain direct estimates of the ...

Abstract: Finite-element (FE) simulations are increasingly providing a versatile environment for conducting lateral ground deformation studies. In this environment, mitigation strategies may be assessed in order to achieve economical ...

Abstract: Internet technologies are employed to allow real-time video monitoring, control, and execution of bench-top shake table experiments. Structural models of relevance to education in dynamics and earthquake engineering can ...

Abstract: In saturated clean medium-to-dense cohesionless soils, liquefaction-induced shear deformation is observed to accumulate in a cycle-by-cycle pattern (cyclic mobility). Much of the shear strain accumulation occurs rapidly ...

Abstract: For large embedded structures, soil-structure interaction (SSI) plays a major role in dictating the overall seismic response. In light of recent strong seismic excitation affecting such structures, three-dimensional (3D) ...
