To　explore　the　potential　application　of　concrete-filled　double-skin　steel　tubular　(CFDST)　structures　in　wind　turbine　towers,　this　study　carried　out　wind　tunnel　tests　to　explore　the　aerodynamic　behavior　of　CFDST　tower-based　wind　turbine　systems.　Two　scaled　models　including　traditional　steel　tower-based　and　CFDST　tower-based　wind　turbine　systems　were　designed　and　tested　in　the　field　of　typhoons.　Then,　the　vibration　characteristics　in　both　the　downwind　and　crosswind　directions　were　systematically　investigated,　in　terms　of　acceleration　and　displacement　response,　motion　trajectory,　dynamic　characteristics,　etc.　The　findings　demonstrate　that　CFDST　structures　can　have　significantly　improved　performance　against　both　blade　harmonic　excitation　and　external　environmental　excitation.　Compared　to　traditional　steel　towers,　CFDST　towers　exhibit　a　substantial　reduction　in　aerodynamic　response.　In　particular,　the　reduction　in　the　RMS　value　can　be　over　five　times　in　the　resonance　case　and　457.69%　in　the　non-resonance　case.　The　CFDST　towers　predominantly　exhibited　converged　motion　trajectory　and　concentrated　on　lower　vibration　modes.　The　energy　dissipation　capability　was　remarkably　enhanced,　with　the　damping　ratio　increasing　up　to　40.98%.　Overall,　it　was　experimentally　demonstrated　that　CFDST　towers　can　efficiently　address　the　dynamic　problems　of　large-scale　wind　turbine　towers　in　engineering.　©　2024　by　the　authors.
