STUDY OF EQUIVALENT MODEL OF HIGH-RISING TOWER STRUCTURES ON THE BOLT LOOSENESS
The flange joint is a common connection form of high- rising steel tower structure, and bolt looseness on the joint of flange is the damage with facilitated occurrence in the structure. If damage occurs and develops continually, the structure would be in danger. Apparently it is necessary to find out the looseness damage and renovate it timely. The influence of bolt looseness on the flange on the stiffness of structure is investigated in this paper, and the finite element model of high-rising steel tower structure with bolt looseness is established according to its damage characteristic by adopting the optimization equivalent method, which provides the solid foundation for the establishment of damage detection system of bolt looseness on the high-rising steel structure.
