Non-linear Static Procedures (NSPs) have become widely accepted for use in seismic design and evaluation in recent years. While generally acceptable for peak displacement estimates, the accuracy of the NSPs is poor for quantities that are significantly affected by higher modes. In recent work performed for the ATC-55 project, a new approach was identified for determining those quantities that are significantly affected by higher modes. The Scaled Non-linear Dynamic Procedure (Scaled NDP) is easily used in conjunction with a NSP for performance-based seismic design and evaluation. The Scaled NDP appears to provide a valid basis for establishing design values at stated levels of confidence using the results of non-linear dynamic analysis. These results can be used to evaluate the performance of a given design as well as to determine the strengths required of members in order to ensure that ductile behavior develops. Suggestions are made for the use of the NSP and Scaled NDP in Performance-Based Earthquake Engineering.
