Experimental static data based damage localization of beam-like structures considering axial load

In this research work, a crack diagnosis method for beam-column structures is proposed considering axial load effects through experimental data. The proposed method is employed for the detection of damage locations including single and multiple damage scenarios considering four cases of simply supported beam-column. The results show that the locations of single and multiple damage scenarios can be well recognized in low axial loads considering random noise effect. However, in the vicinity of the critical load, healthy and damaged static data are uncommon. On the other hand, increasing the axial load, especially when it reaches to the critical load, has a negative effect on the static responses that is precisely considered by the proposed damaged index.
