| Abstract: |
Complex bridges, including cable-stayed and arc-supported structures, require meticulous planning and control during staged construction to maintain adherence to the original design. Deviations due to erection errors, tolerance effects, or survey discrepancies pose significant challenges. This study introduces innovative geometry control applications, illustrated by the Thu Thiem 2 bridge in Ho Chi Minh City, Vietnam. Initially fixed construction plans, including camber and cable stressing forces, were dynamically adjusted in response to real-time deviations and load changes. A critical innovation, the "KINK" feature, was developed to integrate survey data and correct cumulative installation errors, improving the fidelity of the 'as-built' analysis, and allowing for proactive design modifications. Our research enhances the precision and efficiency of bridge construction and supports improved collaboration among stakeholders. |
