DAMAGE IDENTIFICATION OF ACTUAL BRIDGE BASED ON SUBSPACE ROTATION ALGORITHM
【摘要】：正 Now damage identification method based on parametersof structural model is one of the hotspots. SubspaceRotation algorithm introduced in this paper belongs to thedamage identification method based on parameters ofstructural model.Subspace Rotation algorithm separatesthe damage location and damage extent problems and iscomputationally inexpensive. Subspace Rotationalgorithm is used to detect damage of actual bridge in thispaper and practice testifies that Subspace Rotationalgorithm is feasible and simple for damage identificationof actual bridge. Now it is few that damage identificationis used in practice of civil engineering. Therefore, this isonly a try in this paper and there are many things to bedone in this field.
