Tuned mass dampers (TMDs) are used to reduce dynamic vibrations of structures under environmental loads such as wind or seismic excitation. In this paper, the optimum design of nontraditional tuned mass dampers (NT-TMD) attached to a damped main structure under harmonic excitation was investigated. Unlike the traditional TMD, the damping element in NT-TMD is directly connected to the ground. In this study, the effectiveness of NT-TMD on the attenuation of vibrations on the damped main system under harmonic load is investigated. The optimum parameters of the NT-TMD are obtained by using the hybrid pattern search (HPS) technique. According to numerical results, it is seen that non-traditional TMD is more effective than traditional TMD in reducing vibration.
Ayarlı kütle sönümleyiciler (AKS) rüzgâr ve sismik etkiler gibi çevresel yükler altındaki yapıların titreşimlerinin azaltılmasında kullanılmaktadır. Bu yazıda, harmonik etki altındaki sönümlü bir ana yapıya eklenen geleneksel olmayan ayarlanmış kütle sönümleyicilerin optimum tasarımı araştırılmıştır. Geleneksel AKS’den farklı olarak, sönüm elamanı direk olarak yere bağlanmaktadır. Geleneksel olmayan AKS’nin optimum parametreleri hibrit model arama tekniği kullanılarak elde edilmiştir. Numerik sonuçlar titreşim azaltılmasında geleneksel olmayana AKS’nin geleneksel AKS’ye göre daha etkili olduğu görülmektedir.
