A method for rapid estimation of dynamic coupling and spectral responses of connected adjacent structures

A simple method is presented for estimation of dynamic coupling and maximum seismic responses of structures connected through links. The purpose is preparing a simple measure for distinguishing the cases where two connected structures interfere in the response of each individual structure and incorporating such cases in spectral analysis. First, each structure is analysed independently, and the natural modes with considerable interference with the other structure are identified. Then the spectral responses corresponding to such modes are modified in modal space. It is shown that the proposed method can estimate the spectral responses of adjacent systems with good accuracy.
