    Abstract

    Boundary conditions in dynamic centrifuge model experiments are very important as we seek to simulate the semi-infinite extent of a soil stratum. This paper concentrates on model containers designed for uniaxial horizontal shaking. The first section will describe the novel features of a new free-moving laminar box built at Cambridge. The second objective of the paper is to compare the behaviour of this zero natural frequency, low inertia container with that of an equivalent shear beam container. The dynamic performance is assessed in terms of instrument readings at the box centre and near the boundary, their phase lags, and their frequency transfer functions, for different soils. Both containers show little difference between box centre and end-wall for dry soils. However, the laminar container is shown to provide a slightly superior match even when the ESB is operating under design conditions.
