Operational modal analysis using forced excitation and input-output autoregressive coefficients *

Abstract

This study focused on the damage detection of reinforced concrete bridges. First, autoregressive coefficients (ARCs) are computed for the intact and the damaged structure. Autoregressive (AR) models are regarded between the most accurate methods to represent a stationary output time-series. The system is analyzed with different p-lags in each time interval… (More)
