Numerical study on the optimal effective damping ratio of lead-rubber bearings in RC shear-wall structures under far- and near-fault earthquakes

Key Points

• Optimal effective damping ratio improves shear-wall performance during seismic events,
• Numerical simulations reveal a significant impact on structural response under varying earthquake conditions.
• Analysis of lead-rubber bearings focuses on their effectiveness in absorbing earthquake energy in reinforced concrete structures.
• Results suggest improved design guidelines for earthquake-resistant structures using lead-rubber bearings.
