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 ,为进一步提高工程抗震设计水平提供理论依据
Earthquake is generally believed that the damage caused on the ground surface is mainly the level of the S-wave vibration, seldom consider the role of seismic vertical force. The effect of seismic force alone can not reflect the characteristics of earthquake damage comprehensively. Proposed impulse method to study the calculation of vertical seismic force. By studying the distribution of maximum vertical seismic force, the influence and damage of vertical seismic force on buildings are discussed, which provides a theoretical basis for further improving the seismic design of the project
