The objective of this publication was to develop a procedure to establish consistent and rational building system performance and response parameters (R, Cd, Ω0) for the linear design methods traditionally used in current building codes. The primary application of the procedure is for the evaluation of structural systems for new construction with equivalent earthquake performance


Quantification of Building Seismic Performance Factors presents a recommended methodology for reliably quantifying building system performance and response parameters for use in seismic design. The parameters or “seismic performance factors” addressed include the response modification coefficient (R factor), system overstrength factor, and deflection amplification factor. The methodology is a refinement of an earlier preliminary methodology, and is based on a review of relevant research on nonlinear response and collapse simulation, benchmarking studies of selected structural systems, feedback from an expanded group of experts and potential users, and evaluations of additional structural systems conducted to verify the technical soundness and applicability of the approach
