Seismic response of low-rise steel structure isolated using low damping steel-reinforced elastomeric bearings
Seismic isolation has attained recognition as an effective way of reducing the earthquake induced damages to structures. However, most common seismic isolation devices are too expensive and complex to produce, furthermore, they are generally used for structures of high importance or tall structures. Introducing and evaluating the response of a low-cost seismic isolation for general middle-and lower-class community constructions is the aim of this study. To do so, low damping steel-reinforced elastomeric bearings (SREB) are chosen as the seismic isolation device. A typical three storey steel structure was considered for the investigation. The three-dimensional model of the structure was developed and analyzed with and without the SREBs. The results indicate the improved performance and significance damage mitigation of the SREB equipped structure compared to the non-isolated structure.
