Abstract
This article takes the steel structure roof of Nanchangdong Railway Station as an example to study the sliding construction of large-span steel structures.The roofs is divided into several sliding zones,after assembling each sliding zone,it is gradually slid to the design posi-tion with the help of sliding driving equipment.During the sliding construction process,finite element software is used to conduct finite element analysis on typical slip conditions during the sliding construction process,and the horizontal thrust during the sliding process of the"triple arch"element is provided,providing technical support for the transformation of the"triple arch"element system and the sliding construction process.关键词
