动荷载是由于地震力、不稳定的风、冲击波，往复式机器所产生。
Dynamic loading is produced by seismic forces, non-steady wind, blast, reciprocating machinery.

如果该非线性分析收敛失败，包括检测出结构不稳定，则用旧的荷载比乘以备份比，来计算新的荷载比。
If the nonlinear analysis fails to converge, including the detection of a structural instability, a new Loading rate is compute by multiplying the old rate by the Backup rate.
