The engineer must calculate the live load of the building.

工程师必须计算建筑物的活荷载。

During construction, changes in the live load are inevitable.

在施工过程中，活荷载的变化是不可避免的。

Calculating the live load is crucial for ensuring building safety.

活荷载的计算对于确保建筑安全至关重要。

The live load includes the weight of people, furniture, and equipment.

活荷载包括人、家具和设备的重量。

The designer needs to consider the impact of the live load on the structure.

设计师需要考虑活荷载对结构的影响。

Then calculate vertical load ( constant load and live load ) under the Internal Forces.

接着计算竖向荷载 ( 恒载及活荷载 ) 作用下的结构内力.

The increase in nominal stress due to live load, BC, is usually small in comparison with the dead load, OA.

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.

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。

So the structure can only take on the displacement produced by the live load.

随后紧固各支座固定螺栓,结构使用时支座仅承担活荷载作用产生的位移.

The fatigue life of railway bridge mostly lies on the constructional details of the bridge structure, characteristics of live load action effect, and times of live load actions.

铁路桥梁结构的疲劳寿命主要取决于桥梁结构构造细节、活载作用效应特征和活载作用次数。
