Experimental methods complemented by numerical verification is appropriate tool for investigation of the dynamic behaviour of soil. In this paper, comprehensive experimental program, on new type of sand was performed to upgrade the understanding of the dynamic behaviour of cohesionless soil. The performed research at first, deals with the main aspects in the process of design, construction and installation of the laminar box in the Laboratory for Dynamics of Soil and Foundation at the Institute of Earthquake Engineering and Engineering Seismology in Skopje, Macedonia, and second, involves characterization and definition of the dynamic parameters and liquefaction susceptibility of Skopje sand, which is used in the model testing, by an element testing program sustained of series of triaxial, cyclic tests, and dynamic simple shear test. Detailed investigations were performed to define the key parameters and criteria, which laminar boxes as experimental tools have to satisfy in order to enable representative shaking table tests on large geo-models. Model tests in the designed laminar box were performed on shaking table, which are not presented in this paper. Shaking table tests have the advantage of well controlled large amplitude, multi-axis input motions and easier experimental measurements and their use is justified if the purpose of the test is to validate the numerical model or to understand the basic failure mechanisms.
