Abstract

The article refers to construction of shell filled with soil facilities. The main advantages of this type of structures is the minimized use of new materials and the utilized composite action of materials forming the structure. The construction heavily utilizes the soils directly at the building site. These structures have to resist external horizontal loads under the action of its own weight without overturning for their stability and sustainability. The lateral loads can be caused by soils, berthing impact, and mooring forces, and the structure's capacity can be modeled under these horizontal loads. The purpose of this study is to develop a theoretical model to predict the structure's response to the applied horizontal loads and to verify the model by finite elemental modelling and analysis. The finite element modelling and analyses were performed by using ANSYS / LS-Dyna software to verify the theoretical model. The theoretical model is developed through the use of failure planes based on the limit equilibrium conditions. The minimum horizontal load that causes overturning of the shell is calculated using the theoretical model and then is confirmed by numerical simulations. The results of the numerical simulation are correlated with the results of the theoretical model. Discrepancies between the theoretical and numerical modelling results are presented, and possible causes of the discrepancies are discussed. The study helps to provide a good understanding of the mechanisms involved in the overturning stability of these structures. It is also useful for the theoretical model development and can be utilized in the design of these structures.
