本课程论文采用软件是MATLAB R2010a，所编程序应用的方法是线性加速度法。程序采用的是两层循环上实现位移谱的求取。内循环实现在地震波下由上一步所得到的位移、速度和加速度得到下一时间间隔后的位移速度和加速度；外循环实现在不同结构自振周期（频率）下遭遇地震波的响应。本文在求出相对位移反应谱的同时，也求出了相对速度反应谱、绝对加速度反应谱。
English Description：
The software of this course paper is matlab r2010a, and the programming method is linear acceleration method. The program uses two-layer cycle to get the displacement spectrum. The internal circulation realizes the displacement, velocity and acceleration obtained from the previous step under the seismic wave to obtain the displacement, velocity and acceleration after the next time interval; The response of the structure encountering seismic waves under different natural vibration periods (frequencies) is realized by external circulation. In this paper, the relative displacement response spectrum, the relative velocity response spectrum and the absolute acceleration response spectrum are obtained.
