以楼层谱为目标拟合出的人工波,一般被作为核电设备抗震安全评价的重要输入数据。对于那些形状复杂特殊、拟合精度要求较高的楼层谱,通过将频域中的调整傅里叶幅值与时域中的叠加窄带时程方法相结合,提出了一套综合算法。最后,通过实例验证了该算法的有效性。 Artificial waves, which are fitted to the floor spectrum, are generally regarded as important input data for the seismic safety assessment of nuclear power plants. For those floor maps with complex shapes and high fitting accuracy, a comprehensive algorithm is proposed by combining the adjusted Fourier amplitude in the frequency domain and the superposition of narrowband time-history in the time domain. Finally, the effectiveness of this algorithm is verified by an example.
