Abstract

Performance of Footing-Soil Interaction (FSI) system with thin layer interface is still an active field of research because the behavior of FSI mainly depends on behavior of interface and its influencing thickness. Many researchers performed FSI study with commercially available software with available zero thickness interface element. It has been observed the disadvantages such as numerical ill-conditioning, difficulty in meshing, difficulty in identification of stresses and displacements at junction nodes and unexplored the realistic modeling of physical system. The disadvantages in using zero thickness interfaces have been overcome by implementation of thin layer interface. It is realistic to use thin layer interface because there always a thin shear zone formed in soil just near footing due to displacement of footing/structure. The computational difficulties have been automatically nullified by considering the finite thickness at interface. Also it is very easy to monitor the interface for stress analysis. Thus in order to understand the execution and performance of thin layer interface, this paper focuses on the comparison of zero thickness and thin layer interface in FSI modeling with soil linearity and non-linearity. The output in terms of displacements and stresses at footing-soil interface has been represented for comparison. The results show the effectiveness of thin layer interface as an alternative modeling consideration to zero thickness interfaces for FSI analysis.
