竖向地震力的冲量计算法

The Calculate Method of Impulse for Vertical Earthquake Force

一般认为地震在地表面引起的破坏主要是S波的水平震动 ,很少考虑地震竖向力的作用。单从考虑地震水平力的作用是不易全面反映震害特征的。提出用冲量法来研究计算竖向地震力。通过对最大竖向地震力分布研究 ,探讨竖向地震力对建筑物的影响与破坏 。

It is generally considered that the destruction in earth surface is caused by horizontal vibration of 'S' wave and seldom considered the effecting of the earthquake vertical force. It can not reflect the character of the earth calamity completely only by considering the horizontal force of earthquake. In this article, the impulse method is put forward to study and calculate the vertical earthquake force. It discuses the building destruction and reflection cause by vertical earthquake force through analyzing the distribution of max vertical earthquake force , which supplies the theoretical basis for improving the design level of resisting the earthquake.
