Abstract: Discussion on the checking calculation ways about muti-span monorail beam, which is used in hanging airplane dock. And introduce the checking calculation process about three equal span I-steel monorail beam with actual engineering, to judge whether the type of the selected monorail beam satisfied the design requirements. it can be referenced by the same design.
