000010854 520__ $$2eng$$aNonlinear response-history analyses are used by the engineering community as the most reliable technique to estimate structural behaviour. In such analyses, besides an adequate structural model, a set of acceleration time-series is needed as the most realistic representation of the seismic action. Hence, the issue of adequately selecting and scaling an assemblage of ground-motion records that could enable a dependable determination of structural behaviour with fewer number of runs is of critical importance. In this paper, the possibility of using the outcome of equivalent SDOF models as an additional criterion for selecting and scaling real records for nonlinear analyses of buildings has been studied through extensive nonlinear response-history analyses over a wall-frame building. In general, the inclusion of equivalent SDOF peak roof drift estimates as an additional selection parameter proved useful in reducing the variability and improving the median estimate of global structural response. Finally, a simple yet effective method for selecting and scaling ground-motion records is proposed.
