“…Finally, the components are installed and secured. It is important to note that for ease of installation after hoisting, the assembly platform is generally positioned directly below the installation location [13][14][15][16]. Once assembly is complete, the entire structure is hoisted to the designated height using lifting equipment.…”

This paper explores the lifting project of a steel structure corridor in the Haiyue Center, Quanzhou City, with a focus on mechanical response, safety, stability, and construction guidance under wind load conditions. The investigation attends to safety apprehensions stemming from the absence of horizontal constraints within the corridor, rendering it vulnerable to wind-induced loads. Measures are implemented to prevent collisions with nearby buildings during lifting. Stability challenges, including beam displacement and excessive stress, are examined. Anti-deformation trusses and inclined web rods are employed to ensure stability, prevent potential instabilities, and promote uniform deformation. The study also analyzes stress during asynchronous lifting. Through the enforcement of stringent parameters, where asynchronous displacement is confined to a maximum of 25 mm and asynchronous lifting load is limited to 20%, the structural integrity of the corridor is meticulously upheld. This judicious approach serves to not only avert deformation but also to forestall structural impairment. Therefore, the significance of stress distribution and deformation is emphasized when conducting the integral lifting of steel structure corridor between two super-tall buildings under wind load conditions. Simultaneously, relevant construction control measures have been devised, along with offering scientific recommendations for similar cases involving lifting construction processes under the influence of wind.

When constructing long-span spatial steel structures, the unformed structure is often incomplete and unstable. The construction sequence significantly influences the mechanical state of the structure during the construction stages (CSs), affecting both the path and time effects. This study examined the mechanical properties of the construction process using an actual project as a case study, comparing two methods: one-step forming and stage-by-stage forming. Critical turning points of stress and displacement during the CSs were identified as the initial installation and unloading stages. Stress concentrations frequently occurred at temporary support points, and peak displacements often appeared at the outer overhanging bars of the structure. A well-planned construction sequence can effectively manage the structure’s formation, boundaries, and loading to ensure construction safety and stability. The conclusions and analysis methods from this study provide valuable references for the design and construction of similar long-span spatial steel structures.
