چکیده مقاله
The aim of this paper is to propose a simple and reasonably accurate method for determination of modal periods of structure including soil foundation structure interaction SFSI effects Mylonakis and Gazetas 2000 reported that Mexico earthquake was particularly destructive to 10 12 storey buildings founded on soft soil clay, whose period increased from about 1 0 s assumption of fixed base structure to nearly 2 0 s due to the SFSI This conclusion demonstrates the effects of higher mode on the response of structure In this paper, The results indicate for a constant depth of embedment and soil shear wave velocity, the actual modal period become a few smaller than proposed method of modal period and the proposed mode is efficient in the modal analysis
