设备振动荷载对转运站结构设计的影响

Influence of equipment vibration load on structural design of transfer station

港口工程中的转运站内设置有各种工艺设备,这些工艺设备荷载较大,设备运行所产生的振动荷载会对结构产生较大的影响。若结构整体布置、构件断面设计不合理,将会影响结构的使用性能,甚至会对结构安全造成影响。设备振动荷载对结构设计的影响分为3部分:对荷载取值的影响、对构件设计的影响、对结构整体设计的影响。转运站的振动控制应主要控制水平振动位移。提出转运站考虑设备振动荷载影响的设计原则与计算方法,并针对减小设备振动对结构受力、使用性能的影响提出建议。

In port engineering, transfer station＇is generally provided with a variety of processing equipment, which is with high vibrating load and thus has apparent effect on the structure. If the arrangements of the structure and member section are unreasonable, it will affect the structure performance, even the safety of the structure. The influence of equipment vibration load on the structural design is divided into three parts： effecting on load, component design, structure overall design. Transfer station vibration control should be mainly controlling the horizontal vibration displacement. Design principles and calculation methods of transfer station considering the equipment vibration load effect is provided. Rational suggestions about the influence of reducing device vibration on behaviors of structure performance are proposed.
