Study on Sliding Construction Technology of Complex Steel Structure Roof System: A Case Study of Xiamen, China

The construction of a steel structure roof is typically an exceedingly intricate system engineering, with exceedingly elevated technical and managerial demands throughout the course of construction. The insufficiency of engineering proficiency frequently hampers the construction timeline, resulting in substantial monetary losses and amplifying the likelihood of safety incidents. Therefore, predicated on the roof construction project of Exhibition Hall 3 of Xiamen New Convention and Exhibition Center, this paper introduces a two-stage planning and analysis technique for technical solutions. In the initial planning stage of the technical proposal, the pros and cons of the installation approaches for large span intricate steel structure roofs were scrutinized, and after comparative analysis from five dimensions, the “sliding assembly jig frame method” was ascertained as the technical proposal for the project. During the implementation and planning stage of the technical proposal, the construction procedure and approach were clarified, the lifting structure was split, and the type of lifting equipment was selected. Finally, critical construction steps were analyzed through MIDAS/GEN simulation to authenticate the safety of the technical proposal. The research outcomes indicate that the two-stage planning and analysis technique for technical solutions posited in this paper can markedly abridge the construction timeline, save expenses, ameliorate construction quality, and diminish construction safety hazards.
