An Experimental Study on the Numerical Process of the Acceleration Signal for the Estimation of the Displacement Response of Bridges.

교량의 변위응답 추정을 위한 가속도 신호의 수치처리에 대한 실험적 연구

In this study, the algorithm which can estimate displacements from the acceleration data is developed. For proving the validity of this study, the calculated displacements are compared with the measured displacements through the forced vibration tests in the laboratory. So the sampling frequency and filtering range for the estimation of the displacements are proposed. Finally, these results are applied to estimate displacements from the acceleration data obtained from the real bridge.
