Proposed New Analytical Method of Tower Load in Large-Span Arch Bridge Cable Lifting Construction

The cable lifting construction method is the most widely used for large-span arch bridges. correct calculation and analysis of essential to ensure safety linearity in existing research mainly focuses on scheme finite element There relatively little theory, there no analytical To calculate analyze more quickly accurately, based deformation coordination principle suspension a practical proposed load tower acting by system A bridge under was as case study, correctness verified measuring displacements top. brief description structure, verification method, process presented. displacement results are calculated numerical software SAP2000, actual measured data discussed comparatively analyzed, accuracy also evaluated. show that has sufficient accuracy. undertaken prepare mechanical properties; therefore, applied towers engineering, stability, carrying capacity, analyzed verify whether its properties meet engineering requirements. steel pipe columns buckle prone twisting instability. normal stress tower’s part pressurized rod or bending larger. Wind models design-related recommendations presented this analysis. mechanics study can provide guidance
