摘要：According to the regular pattern of the grid structure truss, learning from the methods applied to composite damage detection, for grid structure, the paper proposed the concept of the amplitude matrix which comes from cross-correlation function of response signals. A corresponding amplitude distribution map can be obtained. The injuries in different position bring different amplitude distribution maps. The damage area would be determined by comparing these maps with the map derived from intact structure. © (2014) Trans Tech Publications, Switzerland.
