Safety of base-isolated building in case of IMPA Ctagainst retaining wall

The objective of this research is to analyse the safety of a base isolated building when is subjected to a resonance response in case of long-period ground motion and when this response induce the impact of the building against surrounding retaining walls. As a fundamental study, response of a target base isolated structure subjected to various earthquake input motions is performed. The analytical model considers a gap link element to study the collision against the retaining wall. Maximum acceleration in upper structure increases in case of collision. This acceleration could originate the overturning of building content like furniture. © 2019 WIT Press
