Abstract:
Earthquakes are natural events that cause widespread destruction, loss of life, and economic devastation. They occur when seismic forces release energy stored in the Earth's crust, generating tremors that can last from seconds to minutes, and can trigger landslides, tsunamis, and fires. To mitigate earthquake damage, innovative solutions 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 such technique. Other methods include seismic retrofitting to strengthen existing structures, using reinforced materials like reinforced steel and fiber-reinforced polymers, and incorporating shock-absorbing systems such as viscous fluid dampers and lead-rubber bearings. Additionally, flexible foundations that allow structures to move with seismic forces, advanced framing techniques like special moment frames and buckling-restrained braced frames, are being utilized. Furthermore, a promising alternative for base isolation is the use of scrap tyre rubber pads (STRP), an eco-friendly, low-cost approach that repurposes waste materials, providing sustainable 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 significantly reduce earthquake damage, protecting infrastructure, and ensuring public safety. In the present study the behaviour of STRP is analyzed using ETABS Software
