ABSTRACT
With the rapid development of large-span architectural facilities, the application of scaffolding support systems has progressively increased. Due to the inherent initial imperfections of scaffolding and the complex mechanical behaviors at connection joints, higher stability requirements are imposed on scaffolding systems. Current analyses of scaffolding support systems predominantly focus on their spatial overall stability, while insufficient attention has been paid to the contribution of the collaborative load-bearing interaction between roof slabs and scaffolding to structural reliability. This study investigates the collaborative load-bearing mechanism between roof slabs and scaffolding, using the Yongchuan District Convention and Exhibition Center project as an engineering case. Through finite element modeling and analysis with ANSYS software under various erection parameters, the moment-rotation curves of connection joints are compared with existing experimental data, validating the reliability of semi-rigid connections in the numerical model. Additionally, considering the stochastic nature of geometric initial imperfections, the influence of two types of geometric initial imperfections on the load-bearing capacity distribution of the collaborative system is quantitatively analyzed. The conclusions provide a rational design basis for roof slab-scaffolding collaborative load-bearing systems and establish a foundation for similar future engineering projects.
