建筑抗震设计中地震作用取值问题初探

Tentative research for value problems of earthquake action in building seismic design

针对抗震设防的目的,分析介绍了几个有关建筑抗震设计的公式,并探讨了不同设计基准期条件下,多遇地震和罕遇地震的地震作用取值的变化情况,指出在其他条件相同时,罕遇地震的破坏作用比多遇地震的破坏作用大。

The formula of some relative building seismic design was analyzed and introduced aiming at seismic resistance, change situation of earthquake action value of frequent and rare earthquake under condition of different design reference period was discussed, and pointed out that the damage of rare earthquake is worse than frequent earthquake when the other conditions were the same.
