Research on Damage Identification of Suspension Rod of Tie Arch Bridge Based on Gray System Theory
The traditional damage identification research often can not be more accurate diagnosis of the tie arch bridge boom damage,by virtue of the tie arch bridge finite element example model,proposed based on the deflection line curvature difference combined with the gray system theory of the bridge boom damage diagnosis method.It is found that the curvature difference of the deflection influence line before and after the damage of the teth-ered arch bridge can accurately locate the damage location,and the location of the curvature difference muta-tion is the damage location of the bridge.The gray correlation coefficient is inversely proportional to the degree of bridge damage,and the larger the gray correlation coefficient is,the smaller the degree of damage is.
