This paper presents a random response analysis of a high-rise building structure with shear type under earthquake ground motion. The frequency response function matrix is derived directly from the equation of motion through the Fourier transform to calculate the self-power spectral density function matrix of the lateral shift and the shear response, and the variance is calculated using the Simpson integral formula. The method of this article is simple and easy to program and easy to program on the computer.
