In t.is st.dy, a t.o-st.ge met.od is present.d for ident.fying mult.ple damage scenarios. In t.e first.st.ge, t.e damage locat.ng vect.r （DLV） met.od using normalized cumulat.ve energy （nce） is employed for damage localizat.on in st.uct.res. In t.e second st.ge, t.e different.al evolut.on algorit.m （DE） is used for damage severit. of t.e st.uct.res. In addit.on, in t.e second st.ge, a modificat.on of an available object.ve funct.on is made for handing t.e issue of symmet.ic st.uct.res. t. verify t.e effect.veness of t.e present.t.chnique, numerical examples of a 72-bar space t.uss and a one-span st.el port.l frame are considered. In addit.on, t.e effect.of noise on t.e performance of t.e ident.ficat.on result. is also invest.gat.d. t.e numerical result. show t.at.t.e proposed combinat.on gives good assessment.of damage locat.on and ext.nt.for mult.ple st.uct.ral damage cases.
