ABSTRACT
In physical modelling, laminar strong boxes are commonly used to allow for deformation comparable to the soil which is subject to shaking at the base of the model. This is achieved with a series of rings capable of sliding over one another. This therefore permits the development of stresses and strains associated with the upward propagation of shear waves and achieve the semi-infinite extent of prototype geotechnical structures, allowing dissipation of energy without significant reflection of stress waves due to rigid boundaries. Unfortunately, due to the requirement of the boundary to be made into separate rings, it is often unable to accommodate a window panel for Particle Image Velocimetry (PIV) analysis, which has become very popular amongst physical modellers. A unique window laminar box was hence developed to achieve both objectives. The design philosophy and construction details, as well as results from dynamic centrifuge tests are presented in this paper.
