The dynamic loads that occur as the structure shakes and vibrates can be significantly higher than the static loads.
结构摇晃和振动时产生的动态载荷可能明显高于静态载荷。

Structural load
Structural loads or actions are forces, deformations, or accelerations applied to a structure or its components.
Loads cause stresses, deformations, and displacements in structures. Assessment of their effects is carried out by the methods of structural analysis. Excess load or overloading may cause structural failure, and hence such possibility should be either considered in the design or strictly controlled.
