可变荷载【variable load】指的是在结构的设计使用期内,其值可变化且变化值与平均值相比不可忽略的荷载。按其对桥涵结构的影响程度,分为基本可变荷载(活载,如车辆、人群等)和其它可变荷载(如风力、汽车制动力等)。
对于与时间参数有关的可变荷载一般选用随机过程模型。
Vehicle load that are relate to time parameter is described as random process model.
楼面均布可变荷载可以理解为楼面各单位面积上同时存在相同的可变荷载。
Uniform live load on floor can be comprehended as there are equal live loads on every inch. of the floor at the same time.
因此,研究铝电解车间操作平台可变荷载的合理折减方法,对这类结构的合理设计具有重要意义。
Therefore, study the reasonable reduction methods of variable load value for operating platform in Aluminum Potroom have great meaning on design of this kind of structures.
