摘要
通过对国内外大量地震记录的比较分析,提出竖向地震作用对结构具有不可忽视的影响。简要叙述了计算竖向地震作用的方法以及竖向地震作用的研究进展。从国内外一些震害现象阐述了结构抗震分析中考虑竖向地震作用的重要性,并归纳了地震分析中的一种新观点。
This paper presents that the influence of the vertical seismic effect on the structure cann t be ignored from a lot of seismic records.The method of computering vertical seismic force and development of researching vertical seismic effect are briefly introduced.The importance of considering vertical seismic effect in structural analysis is discussed from some destroyed phenomenon after earthquake in China and some other countries.Finally,a new advice is induced in seismic analysis.
