Bu makalede, hibrit sismik sönümleyici tanıtılarak iki enerji soğurma sistemi, (iç sistem ve dış sistem) arasındaki boşluğun boyutuna göre verimliliği incelenmiştir. Birbirlerine bir kol yardımı ile bağlı olan bu sistemler tercih edilen çap ve kalınlıktadır. Aynı zamanda kolun işlevi yüksek deplasman olan durumlarda iç sistemi harekete dahil etmektir. Bu çalışmanın temel amacı, yapıların destek sistemi içinde aynı alanı kaplarken, iç sistem adı verilen ikincil bir mekanizma kullanarak halkaları genişletmek ve içindeki alanı arttırmaktır. Bu amaçla, ticari bir sonlu eleman paketi olan ABAQUS / Explicit'te sayısal simülasyon gerçekleştirilmiştir. Çalışmada incelenen modeller, kolun boşluk boyutu dışında damperin tüm kısımlarında aynı büyüklüktedir. Bu parametrenin yük-deplasman eğrileri ve ardından emilen enerji miktarı üzerindeki etkilerini araştırmak için modellerde 0, 5, 10 ve 15 mm dahil olmak üzere dört farklı boşluk boyutu dikkate alınmıştır. Bu parametrenin, boşluk boyutunun iç sistemin devreye girme süresini kontrol ettiği ve ardından iç tüpün de enerjiyi dağıtmaya başladığı gerekçesiyle enerjinin emilmesinde gerçekten etkili olduğu gözlemlenmiştir. Bu, tasarım prosedüründe kilit bir faktör olarak önerilen sistemlerin kontrol edilebilirliğini artırabilir. Boşluk boyutunu 15 mm'den 0 mm'ye düşürerek tam devreye giren sistem ile emilen enerji miktarının %34 arttığı görülmüştür.

Effects of Hybrid Seismic Damper on Energy Absorption Capacity

Yıl 2021, Cilt: 19 Sayı: 1, 35 - 40, 02.05.2021

Öz

In this article, the hybrid seismic damper is introduced, and its efficiency is investigated according to the size of the gap between two energy absorption systems (internal system and external system). These systems, which are connected to each other with the aid of an arm, have different diameter and thicknesses. At the same time, the function of the arm is to involve the internal system for the situations with high displacement. The main purpose of this study is to deform the rings and increase the energy absorption capacity by using a secondary mechanism called the internal system, while covering the same area within the support system of the structures. For this purpose, numerical simulation was performed in ABAQUS / Explicit, a commercial finite element package. The models examined in the study have the same size in all parts of the damper, except for the gap size of the arm. To investigate the effects of this parameter on the load-displacement curves and then the amount of energy absorbed, four different gap sizes were considered in the models, including 0, 5, 10 and 15 mm. It has been observed that this parameter is really effective in absorbing energy because the cavity size controls the activation time of the internal system and then the inner tube also starts to dissipate energy. This can increase the controllability of the proposed systems as a key factor in the design procedure. By reducing the gap size from 15 mm to 0 mm, it was observed that the amount of energy absorbed increased by 34% with the fully activated system.
