AI Technical Summary
The prior art cannot monitor the local deformation of large steel structures under dynamic loads in real time, and lacks the means to actively adjust the support force, resulting in the structure being unable to optimize the overall stress distribution under dynamic loads, affecting its stability and safety.
By installing strain gauge and temperature-sensitive metal strips at key nodes of the steel structure, combining multi-objective optimization algorithms and adaptive PID control, local deformation is monitored in real time and support force is dynamically adjusted to ensure that the resistance value of the strain gauge is within the optimal range, and the expansion of the temperature-sensitive metal strips provides additional support to achieve accurate dynamic load distribution.
Real-time monitoring and active adjustment of steel structures under dynamic loads is achieved, the stability and safety of the structure is improved, fatigue damage is reduced, and service life is extended. It is especially suitable for complex environments such as bridges, high-rise buildings and marine platforms.
