Study of seismic performance of low-cost base isolation system using STRP in multistorey building

Earthquakes are natural events that cause widespread destruction, loss of life, and economic devastation. Theyoccur when seismic forces release energy stored in the Earth's crust, generating tremors that can last fromseconds to minutes, and can trigger landslides, tsunamis, and fires. To mitigate earthquake damage, innovativesolutions are necessary. Earthquake-resistant construction techniques have emerged as effective measures.Base isolation, which decouples a structure from the ground, reducing force transmission, is one suchtechnique. Other methods include seismic retrofitting to strengthen existing structures, using reinforcedmaterials like reinforced steel and fiber-reinforced polymers, and incorporating shock-absorbing systems suchas viscous fluid dampers and lead-rubber bearings. Additionally, flexible foundations that allow structures tomove with seismic forces, advanced framing techniques like special moment frames and buckling-restrainedbraced frames, are being utilized. Furthermore, a promising alternative for base isolation is the use of scraptyre rubber pads (STRP), an eco-friendly, low-cost approach that repurposes waste materials, providingsustainable waste management and affordable seismic protection. By exploring these innovative solutions,helps in improving seismic resilience and saving lives. Effective adoption of these techniques can significantlyreduce earthquake damage, protecting infrastructure, and ensuring public safety. In the present study thebehaviour of STRP is analyzed using ETABS Software
