ESTIMATION METHOD OF ALL FLOORS RESPONSE IN BUILDINGS USING FREQUENCY TRANSFER FUNCTION FROM TWO ACCELEROMETERS RECORDS WITH INPUT/OUTPUT RELATIONSHIPS

Abstract

In this paper, we propose a method of estimating a whole buildings response from only two seismic observation records indicated the relationship between input and output in buildings. This method utilizes data obtained from two accelerometers installed in buildings and a frequency transfer function of multi-degree-of-freedom model based on fast Fourier transform (FFT). Proposed method is applied to actual buildings with seismic observations, the validity of the seismic response estimation method is verified.
