“…The interaction effect varies to the soil slope inclination. The structures without SSI consideration overestimate the forces and underestimate the responses for all inclination support (Ghosh & Debbarma, 2019). The seismic performance of the building with interaction effect is large as compare to inclination (Suryawanshi & Bogar, 2019 ).…”

An increase in economic growth, as well as urbanization in the hilly areas, encourages the construction in the hilly region. Considering this fact the engineers should assure the safety of constructions in the slopy region. To understand the past attempts carried out on the constructions of the building on the slopy ground the systematic literature survey is done which includes the parameters like types of the building suitable for hilly regions, slope inclinations for safe superstructure in seismic events, types of safety measures recommended to assure the safety of superstructure and necessity of interaction analysis for the constructions in the hilly region. The survey so carried out in the paper gives a fair idea about the research gap and thus motivates researchers to carry out future research on the gap identified. Keywords: soil-structure interaction; slopy ground; bracing system; literature survey; equivalent static analysis; hilly region constructions.

“…The interaction between topography and structure is crucial for evaluating the seismic response of buildings located on hillsides, where topography can significantly alter the ground motion amplification pattern. Research has shown that the proximity to crests or valleys can influence the magnitude of the seismic response, requiring an informed and adapted structural design for these specific conditions [24,32,33]. The influence of topography on seismic amplification, combined with soil-structure interactions, highlights the need for more sophisticated design approaches that integrate these effects in a comprehensive manner [33][34][35].…”

Seismic-resistant design incorporates measures to ensure that structures perform adequately under specific limit states, focusing on seismic forces derived from both the equivalent static and spectral modal methods. This study examined buildings on slopes in densely built urban areas, a common scenario in Latin American cities with high seismic risks. The adjustment of high-rise buildings to sloping terrains induces structural asymmetry, leading to plan and elevation irregularities that significantly impact their seismic response. This paper explores the asymmetry in medium-height reinforced concrete frame buildings on variable inclines (0°, 15°, 30°, and 45°) and its effect on their nonlinear response, assessed via displacements, rotations, and damage. Synthetic accelerograms matched with Chile’s high seismic hazard design spectrum, scaled for different performance states and seismic records from the Chilean subduction zone, were applied. The findings highlight structural asymmetry’s role in influencing nonlinear response parameters such as ductility, transient interstory drifts, and roof rotations, and uncover element demand distributions surpassing conventional analysis and in earthquake-resistant design expectations.

“…While designing, it must be noticed that structures on inclines are not the same as those in plain land, i.e. they are exceptionally unpredictable and unsymmetrical in flat and vertical planes Such buildings have mass and stiffness varying along the vertical and horizontal planes; as a result, the centre of mass and centre of rigidity do not coincide on various floors and twisting of structures takes place [2]. Thus, the risk factor of those irregular structures increases abruptly as even the base of those structures becomes inclined at slope [3].…”

This research is an attempt to understand and model the performance of short columns under different ground levels and storey number. This behaviour includes varying axial forced, shear forces, and bending moments under gravity loads. All the results have been taken for the columns at the ground level when the phenomenon of the short column has appeared. To study the performance of short columns under different ground levels and the number of stories, the 3D finite element by sap2000, and multiple linear regression analysis have been used in this study. The results show that the axial force for all types of short columns (internal, edge, corner) increases as the number of stories in the building increases at the same ground level. The effect of changing the number of floors with the same value of ground level is not significant in shear and moment for all types of columns except for the one-story and two-storey buildings. For more illustration, the moment and shear for a building composed of one story is very high compared to the two-storey building where the value becomes significantly low; then become higher again with a 3-storey building and with more stories.
