Overview

Numerical modeling demonstrates altered seismic response in reinforced concrete office buildings, highlighting the superior performance of base isolators over mass dampers.

Key Points

  • Base isolator devices achieve superior base shear reduction compared to a tuned mass damper, while geotechnical flexibility amplifies upper structural drift.
  • Top storey displacement increases from 128 mm to 182 mm under soft soil conditions, demonstrating that soil-structure interaction magnifies building flexibility.
  • Numerical modeling using direct and substructure approaches indicates that pile foundation systems in soft ground effectively reproduce hard soil seismic performance.
