Nonlinear response history analysis is conducted as the most trusted and accurate method in the seismic analysis and design of buildings. Since the selection of appropriate records is inherent in this procedure, numerous attempts have been made to use earthquake records that represent a good prediction of future earthquakes. Scaling existing earthquake records is considered as one of the most important tools to fulfill this goal. This paper introduces a new method for scaling ground motion time histories in which elastic input energy is considered as intensity measure. In the new scaling procedure, the scale factor is obtained by minimizing the residual between the elastic input energy of structures for the desired records and the maximum probable input energy of the target spectrum. The efficiency and the accuracy of the proposed method are evaluated and compared with those resulting from the method of ASCE/SEI 7. The results demonstrate that the records scaled with the proposed method lead to more accurate and efficient demand parameters.

利用结构输入能量缩放地震记录的新方法

在建筑物的地震分析和设计中，非线性响应历史分析是最可靠，最准确的方法。由于选择适当的记录是此过程中固有的，因此已进行了许多尝试来使用代表未来地震的良好预测的地震记录。扩展现有地震记录被认为是实现这一目标的最重要工具之一。本文介绍了一种新的缩放地面运动时间历史的方法，其中将弹性输入能量视为强度度量。在新的缩放过程中，缩放系数是通过使所需记录的结构的弹性输入能量与目标光谱的最大可能输入能量之间的残差最小化而获得的。
