摘要

The faster growth of urban areas, coupled with limited available land, has resulted in the development of densely packed buildings sharing common soil media. This proximity increases soil stress, influencing the deformation characteristics of nearby footings. Hence, there is a need to investigate the effect of structure-soil-structure interaction (SSSI) on the footing settlement. The aim of the study is to investigate the effect of SSSI on the footing settlement of a three-story symmetrical RCC building due to the presence of adjacent building with various height. The vertical and differential settlement of footings obtained from SSSI and soil-structure interaction (SSI) analyses are compared by using the finite element software ANSYS under gravity loading. The findings reveal that SSSI substantially amplifies vertical settlement in footings proximate to adjacent structures compared to SSI analysis, consequently inducing significant changes in differential settlement patterns between footings.
