摘要
文献研究给出了用线性模型曲线理论来计算地震加速度数据的反应谱理论.文献又给出了它的简便算法,但这算法忽视了强震丢头记录中初始点数据一般为非零值的影响.本文为此研究给出了更为普通和实用的包括初始数据点为任意值时的间便算法. 给出算例.将这线性模型理论的反应谱计算结果与作者新近研究的时限光滑化模型曲线精确理论计算结果作了对照,反映出用线性模型理论计算存在误差的状况.
In reference[1]. the theory of calculating response spectra it given by linear model curve using the earthquake accelerogrom digital data. Its simpified algorithm and computing subroutine are given in reference[2]. This simplified algorithm is only suitable for those digital data with zero stanpoint, and in this paper its more general simplified algorithm is studied and given. The computing results obtained by linear model theory are compared with the accurate computing results, exhibiting the condition of possibly produced errors in the cakulation by linear model theory.
