活载 live load
- 活载产生的名义应力的增量BC段与恒载产生的名义应力OA段相比一般是很小的。
The increase in nominal stress due to live load , BC, is usually small in comparison with the dead load , OA. - 在计算活载应力时,常规的平面杆系计算程序采用放大系数的近似处理方法。
Conventional plane frame programs amplify the live load effect using the amplification coefficient when computing the stress of live load. - 计算断裂失稳性时,必须考虑焊接或轧制残余应力,恒载应力和活载应力之总和。
To evaluate fracture instability, the total sum of stresses due to residual welding or rolling stresses, dead load, and live loads must be considered.
