Part of: Structural Safety and Reliability


A dynamic reliability analysis system of arbitrary shaped 3-dimensional frame structures is presented and its use is illustrated in bridge seismic safety assessment. The auto- and cross-spectral density function, including the effect of kinematic interaction, are computed by considering the local earthquake ground motion as a limited-duration segment of a homogeneous random field. The spectral density function of response is computed by the frequency response analysis of a multi-point input system. Reliability is calculated as a first-passage probability, and response non-stationarity is assessed by assuming a time-dependent pseudo-damping parameter.
