Method of locating neutral axis for Detecting Damage of a Structure

摘要

structural damage detection method based on acceleration and strain measurement is started. Damage of the structure detection method based on the acceleration and strain measurements according to an embodiment of the present invention is the strain measurement step along the longitudinal direction of the structure to the structure by attaching a plurality of strain gauge for measuring strain of the structure, the strain measurement step step using the strain measured by the strain calculated based on the displacement of calculating the displacement of the structure, an acceleration measuring step for measuring the acceleration of the structure by attaching the accelerometer to a particular point of the structure, wherein the acceleration measured in the measurement step wherein each of the displacement calculated by converting the acceleration in the acceleration calculation step based on the displacement, the strain based on the displacement calculating step and the step of calculating the acceleration based on the displacement calculated by the displacement of the structure in the frequency domain and compares the primary mode This structure can be included at the time of initial neutral axis of the neutral axis position calculating step for calculating a position to be installed. ;
