The　Canton　Tower　(formerly　named　Guangzhou　New　TV　Tower)　of　610　m　high　has　been　instrumented　with　a　long-term　structural　health　monitoring　(SHM)　system　consisting　of　over　700　sensors　of　sixteen　types.　Under　the　auspices　of　the　Asian-Pacific　Network　of　Centers　for　Research　in　Smart　Structures　Technology　(ANCRiSST),　an　SHM　benchmark　problem　for　high-rise　structures　has　been　developed　by　taking　the　instrumented　Canton　Tower　as　a　host　structure.　This　benchmark　problem　aims　to　provide　an　international　platform　for　direct　comparison　of　various　SHM-related　methodologies　and　algorithms　with　the　use　of　real-world　monitoring　data　from　a　large-scale　structure,　and　to　narrow　the　gap　that　currently　exists　between　the　research　and　the　practice　of　SHM.　This　paper　first　briefs　the　SHM　system　deployed　on　the　Canton　Tower,　and　the　development　of　an　elaborate　three-dimensional　(3D)　full-scale　finite　element　model　(FEM)　and　the　validation　of　the　model　using　the　measured　modal　data　of　the　structure.　In　succession　comes　the　formulation　of　an　equivalent　reduced-order　FEM　which　is　developed　specifically　for　the　benchmark　study.　The　reduced-order　FEM,　which　comprises　37　beam　elements　and　a　total　of　185　degrees-of-freedom　(DOFs),　has　been　elaborately　tuned　to　coincide　well　with　the　full-scale　FEM　in　terms　of　both　modal　frequencies　and　mode　shapes.　The　field　measurement　data　(including　those　obtained　from　20　accelerometers,　one　anemometer　and　one　temperature　sensor)　from　the　Canton　Tower,　which　are　available　for　the　benchmark　study,　are　subsequently　presented　together　with　a　description　of　the　sensor　deployment　locations　and　the　sensor　specifications.
