Such failure modes are possible for seismic loading as ratcheting deformation, collapse and low cycle fatigue. Here, occurrence conditions of these failure modes are not clear. This article investigates numerically the dominant parameters of ratcheting and collapse as the combination of gravity and seismic acceleration.
