【摘要】 本义用Ｍｅｙｅｒ小波作为地震地面运动非平稳过程的小波基，推导出线性多自由度在此小波基下的瞬时功率密度谱，由此求出结构动力可靠度时程，实例表明：这种方法是有效可行的。更多还原

【Abstract】 Meyer wavelet is regarded as non- stationary process for earthquake ground motion wavelet basis, this paper proposes the instantaneous Power Spectral Density for linear mul- ti-degree-of-freedom based on the Meyer wavelet. and also gives structure dynamic reliability history. The example shows that this method is practicable.更多还原
