Seismic response of multi-support structures to spatially varying ground motions considering uncertainty in poroviscoelastic soil media

Key Points

• Seismic response varies significantly under spatially varying ground motions, impacting structural safety.
• The study includes evaluations across different soil types, highlighting variability under certain conditions.
• Analysis of poroviscoelastic soil media indicates distinct responses during seismic events.
• Findings emphasize the need for considering soil uncertainty in engineering standards for multi-support structures.
