We propose a two-step method in this paper for the problem concerned. The method first identifies the structural parameters of a shear building using the LSM (Least Squares Method) from the free vibration part of the measured responses of the structural system. After the structural parameters are identified, we get the unknown ground motion using the SAA (Statistical Average Algorithm) by solving the motion equation. To verify the effectiveness of the method, we simulate the response of a linear 10DOF (ten-degree-of-freedom) shear-type structure excited by ground motions and make estimations using the simulated responses assumed as observed records. The results show that the method has the preferable precision.
