摘要

This paper introduces a probabilistic framework for enhancing the seismic design of structures by incorporating uncertainty quantification (UQ) in response analysis. Traditional design codes, often deterministic, can lead to either overly conservative or unreliable designs. The proposed method integrates uncertainties in vibration periods and damping ratios as random variables, using elastic response spectra and the ASCE 7–16 design response spectrum for a more accurate seismic risk assessment. The framework effectively identifies discrepancies between measured and predicted vibration periods and damping ratios through numerical examples and case studies, highlighting the risk of non-conservative designs with nominal values. It emphasizes the need to account for biases in vibration period approximations as per ASCE 7 to prevent under-conservative designs. This approach allows engineers and researchers to estimate building responses more realistically, which is crucial for appropriate seismic design and performance evaluation.
