Long-span rigid frame bridge long-term deformation prediction method and system
This invention proposes a method and system for predicting the long-term deformation of long-span rigid frame bridges, belonging to the field of bridge deformation prediction technology. Addressing the shortcomings of existing prediction methods in considering the coupling effect of geometric nonlinearity and concrete shrinkage and creep, and lacking dynamic response capabilities to damage events during operation, leading to significant deviations between predicted and actual results, this invention establishes a spatial finite element model and constructs structural equilibrium equations that simultaneously consider geometric nonlinearity and shrinkage and creep effects, achieving synchronous coupling analysis of these two effects. Through benchmark simulation and damage event identification based on a probability distribution model, combined with monitoring data, the model is dynamically corrected for damage and the simulation is restarted, constructing a closed-loop prediction mechanism of identification, correction, and restart. This effectively improves the accuracy and precision of long-term deformation and internal force prediction, and enhances adaptability in complex scenarios.
