且考虑了屋面活载不均匀效应、雪压堆积效应和水平地震作用的影响，荷载组合复杂。

The load combination is complex with consideration of the effect of asymmetry distribution of live load, snow accumulation and horizontal seismic load.

考虑到在水平地震作用下短圆柱形容器的变形，剪切效应起主导作用，因而可用剪切梁变形理论来近似地代替。

Considering the deformation of short cylindrical tank under the horizontal earthquake action, the shear effect is the main factor, therefore, it might be anal zed by shear beam deformation theory.
