- The report presents the results obtained in studies that have been conducted to: (1) assess the reliability of the parameters that have been used to identify the damage potential of an earthquake at a given site; (2) evaluate the reliability of ductility based earthquake-resistant design as the only engineering parameter to reflect the design criteria, the acceptable level or degree of damage and to reduce the yielding strength required on the basis of linear elastic response of structures to critical ground shakings; (3) examine the role and importance of the main response quantities which include drift index, input energy, cumulative displacement ductility ratio, and number of yielding reversals in the formulation of design criteria; (4) estimate the required overstrength for buildings that are designed to satisfy the ATC minimum required seismic forces and discuss their significance in relation to the response modification factor R; and (5) examine the actual seismic demands of structures that have been designed in accordance with the ATC recommended design provisions. Eight earthquake ground motions, including three recently recorded motions that caused significant building damage, were considered.
