The Up and Down motion of the earthquake is usually smaller than the Horizontal motion of it. Therefore, in generally, aseismic design of general structures have been done with the attention to the Horizontal motion so far. However, the special structures such as the Elevated-high way of T-shaped Mono-Column with the large rotary-inertia at the column top will suffer from large effects to the vibration response in case the Up and Down motion put upon the Horizontal motion.Such phenomena is known as the parametric excited response of Mathieu and Hill system when the excited frequency ratio of vertical and horizontal is 2 : 1.Authors verified experimentally that the Elevated high way of T-shaped Mono-Column will vibrate very largely when they suffered from Up and Down motion and Horizontal one simultaneously at the earthquake.

地震的上下运动通常小于地震的水平运动，因此，一般结构的抗震设计都是考虑水平运动的。然而，对于T形独柱高架桥这样的特殊结构，当竖向和水平向激振频率比为2：1时，竖向和水平向激振频率比为1：1时，竖向和水平向激振频率比为1.通过试验验证了T形独柱高架道路在地震作用下同时受到上下运动和水平运动时，会产生很大的振动。
