摘要
在计算反应谱及土层反应时,发现反应谱的形态和大小只受时程的主要部分控制,由此给出主时段的定义和确定主时段的方法。主时段的应用不仅可以大大缩短计算时间,而且能够成为持时的一种有物理意义的度量。
It is found out that the shape and size of the response spectrum is only controlled by the main part of the time interval when calculating the response spectrum and soil layer response. Therefore a concept of main time interval and the method of how to determine the main time interval are put forward. The advantage of main time interval usage is not only in shortening computation time,but also in measuring the duration of strong earthQuakes as a useful tool in physics.
