摘要
本文推导了在多维地震动作用下求解结构随机反应的一种有效方法—“多维随机振动的振型加速度法”,通过算例验证了本文方法的正确性,并讨论了转动分量对结构反应的影响。
In this paper, an effective method for obtaining the random responses of structures is given under the action of multiple seismic excitations-the mode acceleration method of multi-dimensional random vibration. Through numerical calculations, the method given in this paper is verified, and the effect of rotational components on structures is discussed.
