ABSTRACT

With the acceleration of China's building industrialization, prefabricated construction has gradually become a key direction for industry development. Modular prefabricated steel structure housing demonstrates broad application prospects in residential and public building sectors due to its advantages of short construction period, low resource consumption, and strong environmental friendliness. However, the existing technical system still faces numerous challenges in terms of joint connection, construction precision control, and overall performance coordination, which restrict its large-scale promotion. This study aims to systematically investigate the key construction technologies of modular prefabricated steel structure housing, propose optimized solutions, and verify their engineering applicability. By integrating theoretical analysis, numerical simulation, and field experiments, this research focuses on in-depth studies regarding standardization of module unit design, rapid on-site assembly processes, connection methods of critical joints, and structural overall stability. The results indicate that adopting novel semi-rigid connection joints can significantly enhance structural ductility and seismic performance; construction process simulation based on BIM technology effectively improves assembly accuracy and construction efficiency; the proposed modular splitting and integration strategy achieves unity between component standardization and construction flexibility. The main innovation of this study lies in establishing a set of modular prefabricated steel structure construction technological systems applicable to diverse building demands, and verifying their feasibility and economic viability through practical engineering cases. The research outcomes provide theoretical support and practical guidance for advancing technological progress and industrialized development of prefabricated steel structure buildings.
