Resumen:

Link elements are the main components of truss structure, while the damage information of nodes cannot reflect the real link element damage location in truss structure. The damage information of link elements were adopted, and the difference of element strain modes of link element was considered as the damage parameter. Damage shows changes of the signal local characteristics, therefore, the damage location of link element can be located by the difference of element strain mode with wavelet transformation. A truss structure damage detection was analyzed by this method, and the results show that this method can be used to determine location of the single and more damages in the truss structure and these were valuable to the practical project. © 2011 IEEE.
