random ice force 冰力周期
There are two modes of dynamic crushing ice forces on vertical structure: steady state ice force and random ice force.
直立结构的挤压动冰力分为稳态动冰力和随机动冰力两种模式。
The results illustrate that three ice force modes, quasi-static, steady-state and random vibration, could be formed with the increase of ice speed.
结果发现：随着冰速的增加，可以出现三种不同冰力形式并分别引起结构准静态振动、稳态振动和随机振动响应。
