Effect of Soil-Structure Interaction on A Building Frame with Shear Walls

Abstract

The soil conditions highly influence the damage to structures throughout earthquakes. Hence the research on the energy transfer mechanism from soils to buildings during earthquakes is demanding area of study for the high-rise buildings. For the current study, reinforced concrete frames of G+15 stories with shear walls in the buildings were modeled using ANSYS software. The effect of soil-structure interactions was considered as well.  Transient analysis was performed on the three-dimensional frames with shear walls subjected to seismic loading were gauged for the contrast in natural frequency, base shear, roof deflection and Storey drifts. The analysis of results indicates that the behaviour of the structure is very much dependent on the natural frequency of the structure.
