Abstract:
In order to study the digital integration of the optimal design of the jacking formwork system of super high-rise buildings and the intelligent construction on site and improve the material utilization efficiency and structural rationality, taking the jacking formwork steel frame structure used in a super high-rise building in Xi'an as the object, the SIMP interpolation model method was used to constrain the vertical displacement of the cantilever end of the secondary truss, and the optimization was carried out to reduce the steel consumption of the jacking formwork steel frame structure. According to the optimization results, the jacking formwork steel frame structure was designed. The research results of the coordinated development of intelligent construction and building industrialization were applied, and the topology optimization design, systematic installation and intelligent construction were taken as the implementation framework. Through topology optimization design combined with intelligent control operation and other tools, the optimized jacking formwork steel frame structure based on intelligent construction was realized. The application of intelligent construction in various stages was systematically sorted out, and engineering management based on an information model was realized using a construction management platform. The results show that the optimized jacking formwork steel frame structure can reduce the weight of the steel frame by 20% while improving the bearing capacity and stiffness of the structure under the condition of meeting the constraints, reducing the steel consumption of the jacking formwork steel frame structure, improving the efficiency of steel use, strengthening the digital integration of topology optimization design and on-site intelligent construction, and promoting the construction application of intelligent construction equipment.
