It is inevitable that space truss structure will be damaged under wind excited.Due to numerous nodes and bars in the space truss structure

it is unable to identify the structural damage based on measurement response information obtained by arranging sensors on all nodes.Therefore

in this paper

wavelet transform method is used for capturing the high frequency information of structural nodes acceleration response under wind loads.The number of acceleration sensors is determined by rational division of space truss structure based on analysis of influence of bars damage on nodes acceleration response.The damage area in the bars can be identified by lesser sensors measurement information.Then the damaged bars can be easily detected in the damage area of a space truss structure.At last

taking a space truss structure as a numerical example

the damage area identification is carried out by considering measurement noise.The result shows that the proposed method is effective.
