Abstract
The effect of soil-structure interaction on the response of structures to dynamic loads has long been recognized and the deterministic approach is usually used for its evaluation. In most soil-structure interaction analyses, the soil shear wave velocity is used to characterize the stiffness of the soil and the foundation system. In practice, the shear modulus of the soil is difficult to evaluate and the natural spatial variability and the measurement technique affect its measured value. Probabilistic concepts are used to evaluate the significant design parameters of tall structures and to examine the sensitivity of their wind response to the variation of the soil shear wave velocity used in the analysis. In this study, the dynamic response of tall structures and the base bending moment of R/C TV towers, as an example of a tall shell structure, are evaluated accounting for soil-structure interaction. A probabilistic approach is used to account for the uncertainties in the shear modulus of the soil underneath the foundation and the design wind speed on the calculated response and base bending.
