[Abstract]:With the rapid development of social economy, long-span prestressed steel structures are more and more used in large public buildings such as gymnasiums and exhibition centers. However, the large volume and complexity of the structure also bring new problems and challenges to the construction process. In order to solve the problems such as difficult installation and tension of chord beam structure, difficulty of deformation control, low degree of visualization and information in construction management process, the project of Changsha International Convention and Exhibition Center is used as the engineering support in this paper. This paper introduces BIM technology into the construction process of steel structure with chord beam roof, and makes a concrete study on the application of BIM technology in the deep design, simulation calculation, assembly and tension control, construction process management and so on in the construction of the engineering structure. The main research contents are as follows: (1) A brief introduction to the basic knowledge of BIM, including the origin, characteristics, software classification, application and function value of BIM in the construction phase, etc.) the establishment and further design of BIM model are studied. It mainly includes software selection in BIM modeling process, modeling rule formulation, component family library creation and model assembly, etc. On this basis, the model is further designed through node refinement and collision checking. Finally, the BIM model is introduced into the MIDAS/GEN finite element analysis software. According to the construction plan of the project, the mechanical properties of the construction process are simulated and analyzed, and according to the displacement and cable force, the model is imported into the MIDAS/GEN finite element analysis software. The safety and reasonableness of the construction scheme are evaluated based on the calculation results of the sagging degree of the brace and the lateral displacement of the column top. (4) based on the three-dimensional scanning technology, combined with the BIM model and the results of the simulation analysis and calculation of the construction process, The control of pre-assembly and the error analysis of site assembly are carried out. The deformation monitoring of the tension arch of chord supported beam is carried out after the structure tension is completed. And the monitoring results are compared with the simulation results and the traditional total station monitoring data. (5) based on the high visualization and information characteristics of BIM technology, the virtual construction management in the construction process of the structure is carried out respectively. Progress management and cost management and other aspects of the application of research. The research results show that the application of BIM technology in the construction of chord beam roof of this project effectively solves the difficulties and key problems in the construction process of the structure, which can guarantee the construction safety of the structure and improve the construction quality. It is important to reduce the construction cost, which is beneficial to the realization of highly visualized lean construction.
