| 摘 要： | 本文将湖北省丹江坝强震记录作反应谱计算,通过计算和对比,说明目前常用的几种反应谱数值计算法的一般误差状况。得出的结果表明:自振周期低于10倍采样间隔时,数值法将产生较大的(甚至可达一倍以上)误差。这也表明这种数值计算法仅适用于柔性的高层建筑或低振型建筑的抗震计算上。

| Abstract: | In this paper, the response spectra of seismic acceleration (recording at Danjian Dam, Hubei province) are calculated by using some current methods of numerical algorithms,and their errors are described based on the results. As the free vibration period is smaller than ten times sampling interval the errors are larger (even over two times as larger as the spectrum from the numerical algorithms. It showes that the response spectrum numerical algorithms are suitable only for resistance earthquake calculations of flexible or lower vibration model buildings. |
