Design and force analysis of steel truss of intelligent construction machine for super high-rise buildings

Super high-rise buildings are typically located in bustling urban areas. Due to their considerable height and limited construction space, numerous challenges arise during the construction process. To enhance the safety and efficiency of super high-rise building construction, this paper designs an intelligent construction machine steel truss platform suitable for the core tube structure of such buildings. Numerical analyses of the designed steel truss platform were conducted during the construction, jacking, and self-climbing phases. The analysis results indicate that the strength and stiffness of the intelligent construction machine steel truss platform meet the design standards for steel structures, ensuring the overall safety and reliability of the structure. However, stress and deformation are relatively high at the connections between primary and secondary trusses, particularly in the chords and webs, as well as at the joints between truss beams and columns. To facilitate construction and improve structural safety reserves, technical and structural optimization suggestions are proposed based on the analysis results. This study provides valuable insights for the design of similar intelligent construction machine steel truss platforms in engineering projects.
