Efficient Modal Analysis for SSI Systems by Luis Gustavo Lopes Costa is a document available to read on EtoBox.
This paper presents an efficient modal analysis method for analyzing the dynamic response of structures with soil-structure interaction. The method represents interaction effects using a free-field ground motion modification factor derived for each vibration mode of the structure. This allows the modal superposition method to be used within the framework of conventional frequency domain analysis for a fixed-base structure. The method accurately approximates the structural response using only the first few v
