This project is an exploratory research on some basic problems in               earthquake engineering which require considerations departing from              conventional approaches.  The conventional approaches have so far               failed to produce satisfactory results.                                                                                                                         These basic problems under consideration are (1) establishment of a             damageability index as a function of earthquake and structural                  parameters, (2) mathematical analysis of the effects of system                  uncertainty on the response prediction, and (3) comparison of new               hysteretic models with and without non-physical drift or loading i.d.,          to study the effect of initial loading or "back bone" characteristic            on the prediction of system response using the new models.
