Abstract

The paper deals with the prediction of global damage and future structural reliability with special emphasis on sensitivity, bias and uncertainty of these predictions dependent on the statistically equivalent realizations of the fu- ture earthquake. The predictions are based on a modified dough-Johnston single-degree-of-freedom (SDOF) oscillator with three free parameters which are calibrated to fit the displacement response and the damage development in the past earthquake. As a damage indicator, the maximum softening in- dex defined on the variations of the first
