This work presents the numerical analysis and experimental validation of sloshing in rectangular tanks subjected to vertical imposed motions, where the evolution of the free surface is studied. The temporal behaviour of numerical and experimental wave heights is compared for two- and three-dimensions. The tanks have an aspect ratio of 2:1. The numerical analysis uses a code that applies the Particle and Finite Element Method (PFEM). The experiment is performed with an adapted shake table that promotes vertical movement. The experimental data are collected using high-speed cameras located on two sides of the tank to register the free surface evolution, and ultrasonic sensors located at control points in the tanks. For the two-dimensional cases, the behaviour for the first three mode shape is studies. For the three-dimensional cases, the behaviour is studies for the first three mode shape on the wider side and the first mode shape on the narrower side is studied.
