Abstract

Many problems in structural engineering involve interaction between the soil and the structure. This interaction plays a major role in the response of a structure and may alter the magnitude of stresses, displacements and other responses of a structure compared to the non-interactive analysis, where the structure is assumed to have fixed supports and does not undergo any relative motions. In soil–structure interaction (SSI) analyses, the displacements and stress resultants are found to deviate considerably from non-interactive analysis, thereby rendering the non-interactive analysis as non-realistic, and it is necessary to consider SSI in the analysis and design of structures. In the present paper, the response of a structure is studied in reinforced soil–structure interaction (RSSI). Comparative numerical studies have also been carried out by using finite element analyses to study the effects of a 3D frame resting on soil and reinforced soil by developing programmes, RSSI-LIN and RSSI-NLIN. The responses investigated are displacements, stresses in soil and member end actions in the structural members. The present paper discusses the effects of SSI and RSSI analyses on displacements.
