Abstract

The recorded motions by California Strong Motion Instrumentation Program (CSMIP) for seven different bridge systems are analyzed using parametric and non-parametric system identification methods. The results of these analyses include identification of modal frequencies, mode shapes and damping ratios. An excellent fit of the recorded motion in time domain is obtained using parametric methods. Utilizing the results from the identification study, the paper evaluates commonly used bridge design provisions in California.
