The library project of Suqian College new campus is a new type of facade suspension cable⁃steel frame hybrid structure. In order to achieve its smooth construction, a method of using a smallnumber of temporary support frames for continuous construction was proposed. Using SAP2000 software toestablish a finite element model of the structure, a comparative study was conducted on the simulationmethods of the construction process, and key technologies such as the number of temporary supportframes required for turnover, suspension tensioning and the installation sequence of it’ s upper steelbeams were studied. The entire construction process of the structure was simulated and the structuralresponse was analyzed, with a focus on four facade suspension structures. The structural status wasgrasped, and the bearing capacity and deformation were verified. The results indicate that using the two⁃step activation method for new installation units can better simulate the actual construction process. Theuse of a 2⁃layer support frame for turnover construction and the installation of suspension cables before theupper steel beams can smoothly achieve structural construction and effectively reduce the investment insupport frame equipment. During the construction process, the stress, cable tension, and structuraldisplacement of the steel structure are all within a reasonable control range. After the completion ofstructural construction, it is basically consistent with the design status, which verifies the rationality andfeasibility of the construction method.
