Abstract
This thesis presents the effect of soil-structure interaction on tall buildings’ design and straining actions. This investigation was carried out by analyzing a multi-story building via a direct approach using a 3D finite element model for the soils and the structure. The results were compared with traditional sub-structuring methods that use linear subgrade reaction springs to represent the soil. The results were also compared with the less common sub-structuring approach that adopts nonlinear springs to represent the soil-structure interaction. Two parametric analyses were performed under gravity and lateral loads considering different soil characteristics. The effects of soil-structure interaction and the induced and differential settlement were presented for various loading conditions and straining actions on the structure-supporting elements. The conclusions include the limitations and advantages of the common sub-structuring approach and the effects of soil nonlinearity on the behavior of tall buildings and their design.
