【 摘 要 】

The effect of soil structure interaction (SSI) on a single degree of freedom system with and without friction damper is analysed in the paper. The structure with different mass, stiffness and soil conditions was prepared and analysed for ten different earthquake records. Using the non-linear time history analysis, the structural response of a single degree of freedom structure with varying slip load of friction damper was studied. It was observed that the performance of friction dampers is influenced by soil parameters. Also, it was established that an optimum slip load and stiffness of brace changes with respect to the type of soil.
