Most　of　the　mode-based　damage　identification　techniques　have　been　well　verified　by　numerical　simulations.　However,　many　of　them　still　face　problems　when　applied　to　real　measurements　where　noise　is　present.　In　this　paper,　an　experimental　program　of　a　reinforced　concrete　beam　is　aimed　to　establish　the　relation　between　damage　and　changes　of　the　structural　dynamic　characteristics.　A　damage　identification　scheme　is　developed　using　the　mode-based　damage　identification　method　described　in　an　accompany　paper.　The　proposed　damage　identification　scheme　is　applied　to　the　experimental　data　and　the　consequent　results　are　compared.　It　is　demonstrated　that　the　proposal　of　a　realistic　damage　pattern　that　can　describe　damage　by　few　representative　parameters　is　necessary　to　guarantee　the　localization　of　damage.　An　adaptation　of　the　initial　finite-element　model　is　required　to　give　the　best　agreement　with　the　reference　measurements.　A　possible　advantage　of　the　algorithm　is　that　the　modal　forces　can　be　directly　extracted　from　any　finite-element　package　and　the　mode　shape　expansion　is　involved　in　the　damage　identification　scheme　using　a　static　recovery　technique.
