By analysed on vibration theory we knew that the load js a static load in mechanics of materials, when the loaded time is 6-8 times as much than the natural vibration period of the unit of structure.

- 通過(guò)振動(dòng)理論的分析得知;材料力學(xué)中靜載荷的定量標準是:當加載時(shí)間為構件系統的固有振動(dòng)周期的8倍以上時(shí);這種載荷即可認為是靜載荷.
