Pada New Tacoma Bridge (opened 2007) main girdernya terbuat dari space truss jadi VIV tidak menjadi concern, apalagi kekakuan torsionalnya cukup tinggi. VIV countermeasures diperlukan pada jembatan dgn box girder, countermeasure-nya bisa menggunakan fairings, flaps atau TMD.

TMD (Tuned Mass Damper) nya besar ya. Bentuk flaps untuk suppress Vortex Induced Vibration nya seperti apa ya. Apakah Tacoma Bridge yg baru di Seattle juga pakai TMD & flaps. Kalo ada fotonya lebih menarik lagi. Tks. Ind Salam kenal.

They carry the girder load (gravity and traffic loads) and transferring them to the supports (i.e. pylon and tower). The cables are the structural part of the structure.
