Abstract

This study investigates seismic response characteristics of a high-rise RC building with the composite foundation of wall and pile group. The building under investigation has maintained a dense, long-term array of strong-motion observations for over 25 years, including data during the 2011 Great East Japan earthquake. Simulation analyses with input motions in the NS and EW directions are performed. The effective input motion is evaluated from seismic records, and axisymmetric FEM analyses are performed for several cases with the foundation type as a parameter, and influences of foundation types on structural responses are discussed.
