Seismic ground failure potential from liquefaction is generally undertaken in three steps. First, a susceptibility evaluation determines if the soil in a particular layer is in a condition where liquefaction triggering could potentially occur. This is followed by a triggering evaluation to estimate the likelihood of triggering given anticipated seismic demands, environmental conditions pertaining to the soil layer (e.g., its depth relative to the ground water table), and the soil state. For soils where triggering can be anticipated, the final step...

Seismic Design and Detailing of Bridge Columns to Account for Ground-Motion Duration, PEER Report 2021-08

Devastating, long-duration earthquakes such as 2011 Tohoku, Japan, earthquake, and 2010 Maule, Chile, earthquake have proved the importance of considering the duration of ground motion in conducting a seismic demand assessment. This research focuses on using both analytical and experimental methods to study the effect of different design details—confinement spacing ratio and longitudinal bar debonding—and different reinforcement strategies—conventional and high-strength reinforcement—on the seismic response of reinforced concrete (RC) bridge columns under long-duration ground motions. In...

Parallel Level-Set DEM (LS-DEM) Development and Application to the Study of Deformation and Flow of Granular Media, PEER Report 2022-06

We present a systematic investigation of computational approaches to the modeling of granular
materials. Granular materials are ubiquitous in everyday life and in a variety of engineering and
industrial applications. Despite the apparent simplicity of the laws governing particle-scale interactions,
predicting the continuum mechanical response of granular materials still poses extraordinary
challenges. This is largely due to the complex history dependence resulting from continuous rearrangement
of the microstructure of granular material, as well as the mechanical interlocking...
