- Abstract:
-
In this paper,a study on the damage identification analysis of steel gantry structures in large-scalesubstations is put out.The damage diagnosis of steel gantry structures with different damage degree and dffer-ent damage sites are discussed based on the method of element modal strain energy change rate. The resultsshow that,modal strain energy change rate is a sensitive indicator index and it can be used to identify thedamages for the steel substation gantry structure simply and effectively.
