Abstract

In this paper, seven real earthquake records are scaled according to Eurocode 8 design acceleration spectrum by using SESCAP (Selection and Scaling Program). SESCAP is a scaling program based on time domain scaling method and developed by using MATLAB, GUI software. Real and scaled earthquake records are used for linear time history analyses of a six-storied reinforced concrete building modeled as spatial by SAP2000. Eurocode 8 allows the use of real earthquake records for linear and nonlinear time history analyses of structures. In the case of using three earthquake records in linear and nonlinear time history analyses, maximum results of structural responses are used for design of structures. If at least seven time history analyses are performed, the mean responses of the structures are taken into account rather than the maximum results. For the selection of maximum results of structural response from thirty five groups are created by calculating combination of threes of seven real and scaled earthquake records, and another group including all of the seven real and scaled earthquake records are created for selection of mean. Relative floor displacements along X axis of the building are preferred as structural response of the building in this study. It is seen that differences between mean value and maximum value of the relative floor displacements along X axis of the building induced by seven and three scaled earthquake records respectively are less than ones obtained from real earthquake records.
