Structural boundary conditions recognition and damage diagnosis are of important practical value for the studies of strutural dynamic properties in laboratory.

Focusing on the default that in the clustering algorithm based on density the objects are processed from high-density area to low-density area,thereby,the objects with low density can not be identified,a novel clustering algorithm based on boundary identification is proposed through discussing the boundary identification existed in clustering process.

For sake of decreasing classification complexity,a decomposed chunking approach was proposed: first,chunk boundary identification,and then chunk type identification.
