Countermeasures against Design Difficulties of Buildings on Top of Silo in Huanghua Port Phase-3 Project

采用与建筑同高度的两榀大桁架为主受力结构,在其顶部、底部分别设置与之刚接的钢梁作为房屋的横向结构框架。本结构形式有效的解决了在大跨度的建筑物上运行大重量的工艺设备时结构挠度难以控制的问题,可供类似工程的设计参考。

Two large trusses as high as the buildings were used to be primary bearing structures. The top and bottom of trusses were rigidly connected with steel beams, which formed the transverse structure frames of the building. This structure could effectively solve the flexibility control difficulty while heavy process equipment was travelling on the large-span building, which could provide reference for similar projects.
