摘　　要：本文对具有剪切型的高层建筑结构在地震地面运动作用下进行随机响应分析。直接从运动方程经Fourier变换导出频响函数矩阵,从而计算侧移和剪力响应的自功率谱密度函数矩阵,并采用Simpson积分公式求方差。本文的方法简单易行,且容易编程序上机计算。A new method of equation derivation is used in analyzing the random response of shear mode tall buildings under earthquake loading. The matrix of frequency response function is derived from the motion equation by Fourier transformation directly, then the matrices of self-power spectral density function of displacement and shear response are obtained. The variances of the matrices are computed by Simpson's integral method. The present method is simple and can be run on a micro-computer. Its program can be easily compiled.
