Influence of aboveground structure on connected underground structure seismic response within an integrated system
Tunnelling and Underground Space Technology（2023）
Abstract
•Aboveground structure influences seismic response of linked underground structure.•Influence of aboveground structure is sensitive to the input motion frequency.•Low frequency input causes amplification of underground structure response.•High frequency input causes reduced underground response at certain locations.
