DETERMINING A HEALTH CONDITION OF A STRUCTURE

摘要

The disclosure relates to structural health monitoring (SHM). In particular determining a health condition of a structure, such as a bridge, based on vibration data measured of the bridge. Measured vibration data is calibrated (410-450). Features are then extracted from the calibrated data (610-630) and a support vector machine classifier is then applied (720) to the extracted features to determine (730) the health condition of a part of the structure. Training of the support vector machine classifier by a machine learning process (910) is also described.

1. A computer-implemented method for determining a health condition of a part of a structure, comprising:
receiving or accessing vibration data of the part of the structure, the vibration data being measured by at least one accelerometer; extracting a feature of the vibration data based on frequency analysis of the vibration data; and determining the health condition of the part of the structure by a support vector machine classifier based on the feature of the vibration data.
