摘要:
为了进一步提高人造地震动时程对目标反应谱的拟合精度和效率,本文提出了一种人造地震动反应谱非线性拟合方法。在人造地震动反应谱非线性拟合过程中,认为Fourier幅值谱与反应谱调整项之间满足非线性(幂指数)关系。通过比例拉伸和折叠等数值技巧以促使模拟加速度向目标加速度逼近。算例分析结果表明,人造地震动反应谱非线性拟合方法具有一定的精度和效率,不失为地震波人工模拟的一种尝试。
Abstract:
In order to improve the fitting accuracy and efficiency of artificial ground motion time histories to the target response spectrum, a new nonlinear fitness of artificial ground motion response spectrum is proposed. During the fitting, a nonlinear (exponential) relationship between the Fourier transform and the response spectrum adjustments is adopted, and the techniques of partial scaling and fractional folding are used to make simulating acceleration approach to target acceleration. Numerical example demonstrates that the new nonlinear fitness method shows some precision and efficiency, it is a useful attempt to use the new method in artificial-simulated seismic ground motions.
