The examples of recent developments of foundation thin-walled structures and their applications are presented. It is noted that the purpose is to develop a method for conducting experimental studies of contact interaction between a folded shell foundation and a deformed base. The purpose of the laboratory tray research is to determine the optimal characteristics of the suggested foundation design. The article suggested a method for conducting a laboratory tray experiment to compare the operation of two models of folded shell foundations. The main stages of conducting the scientific experiment have been described and the basic principles of selecting materials, devices and equipment for carrying out the experiment have been considered. The conduct of the experiment including data recording for each foundation model has been described. As a result, subsidence data for each foundation model have been obtained. The findings have been analyzed; subsidence graphs for each foundation design have been built. It is concluded that better distribution of external load to the foundation system elements is achieved due to the application of a hinged joint of prismatic folds with supporting beams. It has been found that the chosen parameters of the second foundation model complied with the optimized results of the experiment planning and enabled to demonstrate the properties of the foundation system load redistribution better.
