In this study, a two-stage method is presented for identifying multiple damage scenarios. In the first stage, the damage locating v.ctor （DLv. method using normalized cumulativ. energy （nce） is employed for damage localization in structures. In the second stage, the differential ev.lution algorithm （DE） is used for damage sev.rity of the structures. In addition, in the second stage, a modification of an av.ilable objectiv. function is made for handing the issue of symmetric structures. To v.rify the effectiv.ness of the present technique, numerical examples of a 72-bar space truss and a one-span steel portal frame are considered. In addition, the effect of noise on the performance of the identification results is also inv.stigated. The numerical results show that the proposed combination giv.s good assessment of damage location and extent for multiple structural damage cases.

Bi2Te3-based materials hav. drawn much attention from the thermoelectric community due to their excellent thermoelectric performance near room ***,the stability of existing n-type Bi2（Te,Se）3materials is still low due to the ev.poration energy of Se (37.70 kJ mol-1) being much lower than that of Te (52.55 kJ mol-1).The ev.porated Se from the material causes problems in interconnects of the module while degrading the efficiency.
