NOVEL STRUCTURE DAMAGE BASELINE BASED ON SYMMETRY FOR DAMAGE DETECTION OF TRUSS
Structural Health Monitoring and damage identification are playing an important role in civil engineering in recent two decades. Much more efforts to Structural heath monitoring and damage detection had been made in worldwide range. In general, local and global methods were used to detect damage. For local methods, the potential damage region must be prior to know; but for global methods, comparing the structural dynamic parameters under damaged and undamaged state, damage can be identified and located. That is to say, when using global method to identify damage the parameters of intact structure are regarded as structural health baseline. But generally, the responses of damaged and intact structure were not obtained under the same noise level. Thus, new health baseline is defined and researched in this paper.
