Abstract: | In the present work soil-structure interaction effect is studied modeling the semi-infinite soil media using scaled boundary finite element method. The system of a a five-story framed structure coupled with semi-infinite soil media, subjected to seismic excitation is analysed in frequency domain. The system is sub-structured as near field and far field. The far field is modeled using Scaled Boundary Finite Element Method (SBFEM). This method satisfies the radiation condition completely. The dynamic stiffness matrices are coupled with the dynamic stiffness of the near field. The assembled equations are solved to obtain responses in frequency domain which are finally inverse Fourier transformed to obtain responses in time domain. Soil parameters are associated with considerable amount of uncertainties. Hence, reliability analysis should be performed on the responses. Reliability of responses is computed by quantification of uncertainty in terms of some statistical parameters. For this quantification of uncertainty Rosenblueth's 2K+1 point estimate method is adopted. |
