Abstract: The research presented in this report provides a general method for developing relationships between earthquake ground motion and damage. The motion-damage relationships were presented as fragility curves and damage probability matrices. The major components of the methodology consist of: 1) characterization of the potential ground motions; 2) characterization of the nonlinear response of the structure when subjected to extreme dynamic loads; 3) application of the methodology to reinforced concrete frames; 4) sensitivity studies for different structural attributes; and 5) development of a Bayesian technique to update the motion-damage relationships.
