Uncertainty in Nonlinear SDoF Response Due to Long-Period Noise of Accelerograms
The behavior of nonlinear oscillator deformations due to the long-period noise in strong ground motions is investigated. Inelastic spectral and residual displacements (SDIE and SDR, respectively) are selected to represent the nonlinear deformations of single-degree-of-freedom (SDoF) systems. Within this context, the interaction between these deformation demand parameters and high-pass filtering that is used for removing the long-period noise is examined. Analyses indicate that the high-pass filter values can influence the reliability of SDIE and SDR depending on the recording quality, level of inelasticity and magnitude variations. Usable spectral period ranges are proposed for SDIE through probabilistic methodologies where the adverse effects of high-pass filtering are minimal.
