Scope

Public building large-span concrete structures are widely used in projects such as stadiums, exhibition centers, transportation hubs, theaters, and large-scale commercial complexes. Their structural systems take various forms, including large-span beam-slab systems, truss-beam-slab composite systems, arch-shell and spatial curved systems, mega-frame-conversion structural systems, and prestressed concrete structural systems. Such structures feature large spans, significant component cross-sections and self-weight, complex stress paths during the construction phase, and prominent roles of temporary support systems. Moreover, they are influenced by multiple factors such as the early-age performance of concrete materials, shrinkage and creep, temperature effects, the sequence of prestressing and tensioning, and the settlement and unloading paths of formwork and scaffolding. As a result, structural deformation and redistribution of internal forces during construction are often more sensitive than in conventional structures. Improper construction control may lead to quality and safety risks such as deviations in line and curvature, excessive deflection, structural cracking, abnormal prestress loss, stress concentration at connection nodes, and instability of scaffolding. In severe cases, this may affect the durability, functionality, and service safety of the structure. Against the backdrop of continuously strengthening current engineering construction regulations and management requirements for construction quality and safety, it is urgent to establish operational, quantifiable, and traceable technical specifications for the construction organization and deformation control of large-span concrete structures in public buildings, in order to achieve full-process control of structural performance and line targets during the construction phase. Deformation control not only includes forming line and elevation control, but also encompasses control of the stiffness and settlem
