Effect of Uncertainty in Ground Motion Characteristics on the Seismic Damage of Reinforced Concrete Columns with Isolator

Abstract

Large inelastic response can be developed in reinforced concrete columns with isolator due to the second stiffness of the isolator if columns yield. Effect of uncertainty in ground motion characteristics on the seismic damage allocation and failure mode of reinforced concrete columns with isolator was investigated using incremental dynamic analysis in this study. It was shown that failure mode of the reinforced concrete column with isolator depends on the characteristics of ground motions.
