ABSTRACT
With the continuous advancement of urbanization in our country, the number of super high-rise buildings is increasing day by day. Steel structures are widely used in such projects due to their advantages such as light self-weight, high strength and fast construction speed. However, the construction of super high-rise steel structures is confronted with numerous technical challenges, such as high risks of high-altitude operations, difficulty in controlling structural deformation, and complex node connections, which urgently require systematic research and optimized solutions. This paper aims to conduct an in-depth analysis of the steel structure construction process of typical super high-rise buildings, explore its key construction techniques and quality control measures, and put forward operational optimization suggestions. Reasonable selection of the configuration of hoisting machinery and the hoisting sequence can significantly improve the construction efficiency and reduce the safety risks. The adoption of segmented pre-assembly and three-dimensional laser scanning technology can effectively improve the installation accuracy. The construction simulation and real-time monitoring system based on BIM technology can achieve dynamic management throughout the entire process. The innovation point of this research lies in the deep integration of information-based monitoring methods with traditional construction techniques, and proposes a complete set of technical solutions for the construction of super high-rise steel structures suitable for complex environments. The research results have significant practical value and promotional significance for enhancing the construction technology level of steel structures in super high-rise buildings in China and ensuring the quality and safety of the projects.
