Figure 16: Acceleration on floor (a) 1, (b) 5, (c) 10. The acceleration performance of the systems under the Düzce earthquake is shown in Fig. 16. Similarly, to the Northridge and Irpinia earthquakes, the auxetic-type system experienced significantly lower story accelerations when compared with the LRB and fixed base systems. On the first floor, the auxetic-type system experiences similar accelerations to the fixed base system, marginally exceeding it after t = 13s. As the story height increases, the acceleration in the fixed base and LRB systems increase, however the auxetic system experiences a favourable acceleration for most of the duration of the
