Kinematic and inertial soil-foundation-structure interaction may substantially influence structural performance. There are many parameters in the SFSS that influence the final response, suggesting inherent uncertainty in the solution. The computational effort for performing time history analyses, even for a linear elastic coupled SFSS is important. In order to reduce computational cost without reducing the accuracy of the results, we propose the use of Latin Hypercube Sampling (LHS) technique. Sampling techniques are rarely employed in soil-foundation-structure interaction analyses. However, these methodologies are very helpful, because the analyses determined by sampling can be performed by commercial codes, developed for deterministic analyses without any modifications. The difference is that the number of analyses determined by the sampling size is significantly reduced compared to the one for all combinations of the input parameters.
