UPDATING FUZZY-PATTERN RECOGNITION APPROACH OF BOLT LOOSENESS DAMAGE ON THE JOINT OF FLANGE IN TRANSMISSION TOWER STRUCTURES

摘要：

In this paper, adopting the optimization equivalent method, the finite element model of transmission tower structure with bolt looseness damage is set up according to the damage characteristic of transmission tower structure. An updating detection approach of Fuzzy-pattern recognition based on strain mode is also presented in order to locate the specific bolt looseness damage by the reduplicative detection of distance nest degree and proportion nest degree. Performance of the proposed damage detection approach is demonstrated with analysis of a practical transmission tower structure. The result turns up trumps with certain application value.
