- Abstract
- The report presents formulations for developing fragility curves and damage probability matrices for reinforced concrete frame structures. Three different classes of reinforced concrete frames, based on the story heights, are considered. Ground motion characterization parameters used in this report are the spectral acceleration and the root mean square acceleration. At a given ground motion parameter, an ensemble of ground motions is required for evaluating the conditional probabilities for the different degrees of damage. Autoregressive moving average (ARMA) models and Gaussian stationary models with modulating functions are used for this purpose. The identification of the different degrees of structural damage is carried out based on the structural damage models. Models for characterizing the seismic damage to reinforced concrete structures are reviewed in this report. Constrained Monte Carlo simulation techniques are used for evaluating the fragility curves.
