“…To counteract the creep effect, we subjected the soil to continuous loads for 1, 100, 1000, 3000, 6000, and 12000 days in this case to counteract the creep effect. This period is usually considered adequate to complete primary consolidation and detect the beginning of creep (Al-Shamrani and Al-Mashary, 2003) . Especially when comparing creep rate models of the compressible soil layer, the applied vertical stress affects the observed vertical strain.…”

Soil response and superstructure behavior are two major factors influencing the long-term performance of reinforced concrete (RC) structures. Maintaining the structural integrity of these structures over time is crucial due to the complex static interactions between the soil and the structure. This study uses a finite element model to examine the stability of RC structures, considering the long-term static interactions between the nonlinear behavior of the soil and the structure. Numerical simulations are performed on real RC beam constructions at serviceability limit states (SLS) under various loading scenarios in both homogeneous and heterogeneous soil conditions. The parametric study's results indicate that soil heterogeneity and static soil-structure interactions significantly influence the design of RC structures. The nonlinear behavior of the soil over time intensifies these impacts further. This study shows how important it is to think about different types of soil and how they interact with structures when they are not moving. This is especially true when it comes to soil that is easily compressed and changes shape over time in a nonlinear way. By incorporating these factors, the research highlights the critical need to integrate soil heterogeneity and static interaction into the design process to ensure the stability and safety of RC structures. Ultimately, the results demonstrate that accounting for these complex interactions can greatly improve the durability and reliability of RC structures in diverse soil conditions.

“…Frequently the researchers have been focused on slip and bonding analysis in interface [16][17][18]. Debonding has been unexplored due to occurrence of numerical ill-conditioning [19][20]. Interfaces were also used as a geometric attachment to various dissimilar materials where relative motion is not of great importance [21][22].…”

The finite element (FE) modeling of interface in Soil-Structure Interaction (SSI) problem is most important aspect from early days of modeling i.e. during 1960. The overall performance of the structure is completely influenced due to behavior of interface. Such as realistic interface modeling of SSI system subjected to lateral loads leads to appropriate evaluation of lateral sway and base shear stress. During recent times, many modifications have been done in interface modeling such as incorporation of slip and bonding effects. Also the interface joining variable degrees of freedom system (interface for solid to skeletal contact) has come into existence. Still the de-bonding behavior, interface nonlinearity as well as modification in solid to skeletal contact has been unexplored in literatures. Hence there is necessity to develop a FE-SSI model and to study the influence of interface in SSI system considering unexplored features. In this paper, an attempt has been made to show the influence due to interface (including de-bonding and non-linearity) in FE modeling of SSI system using modified 5 noded zero thickness interface element. The performance of modified interface element is a novel contribution in present paper. The present study is limited to static loading conditions only. The effect of interface has been studied by determining bending moment, lateral sway, base shear stress and footing settlement in structure. The inclusion of modified interface has improved the performance of structure by reducing the base shear stress and allowing the sway. Also the true redistribution of bending moment has been observed after considering the modified interface.

“…As shown in Figure 6, the lateral displacements of none of the frames of type 111 exceed the limit (labelled S.O. limit), which requires the second order analysis [6]. Therefore the frames of type 111 can be defined as non-sway.…”

“…Although a number of existing works deal with column base stiffness [3] , [4] and [5], only very limited information is available on possible soil-structure interaction effects on the distribution of forces and the stability of the frame. It is clearly shown in [6] and [7] that soil-structure interaction effects cannot be neglected. Single-storey buildings typically incorporate steel sheeting as a roof deck, which can be applied as a diaphragm to transfer lateral loads to vertically braced bents.…”

The behaviour of steel frame structures including soil-structure interaction, column base connection rigidity and diaphragm effect of the corrugated roof sheeting has been investigated. The frames are evaluated with common soil characteristics and column base configuration. The influence of vertical bracing stiffness is also studied. Second-order effects are taken into account using non-linear analysis. The present study is limited to single bay single storey frames subjected to static loads. It has been shown that using simplified calculation model might cause deviations from the real structural behaviour and in some cases results were non-conservative.
