| 摘 要： | 分析了结构地震反应分析中的反应谱理论,分别得出了绝对加速度反应和伪加速度反应的公式。通过Matlab编程,在El Centro(1940,NS)地震波作用下,对结构的绝对加速度和伪加速度反应进行了比较分析。同时按照规范的设计反应谱对结构不同阻尼下和不同场地条件下的地震影响系数进行了比较分析。为工程抗震设计提供便捷有效的分析手段。

| Abstract: | The paper analyses the response spectrum theories. The mathematical forms of the acceleration and pseudo-acceleration responses can be obtained. According to the Matlab programming, the acceleration response spectrum is compared with the pseudo-acceleration spectrum, both for E1 Centro ground motion. At the same time, the Seismic influence coefficient curve with different damping and different sites for systems are compared in order to provide references for seismic design. |
