Abstract：Abstract: In this paper, The theory of structural vulnerability is introduced. The vulnerability of several truss structures were analyzed, clustering process and unzipping process were statements and receive a variety of failure scenario. The Analysis of truss structure verify the structure vulnerability theory and provide a model for structural vulnerability. By analysis of stress ratio under load, it is found that the bars which have the larger stress are also relative to deteriorating bars in structural vulnerability. It provides a new approach for structural vulnerability analysis. By analyzing the structure of the limit load under the action of concentrated force and vulnerability analysis of characteristic parameters, it is found that if clustering process is similar, the critical load increases with well-formedness.
