Research on Key Technologies of Intelligent Damage Monitoring System for In-service Steel Reinforced Recycled Concrete Composite Structures
The limitation of recycled coarse aggregate has a certain influence on the long-term performance of the steel reinforced recycled concrete composite structures,thereby the long-term performance of the in-service steel reinforced recycled concrete composite structure needs to be further explored.Therefore,based on the computer vision technology,the appearance damage(crack)identification model of the steel recycled concrete composite structure is established.Then,the internal damage change and damage location monitoring model of in-service composite structures is constructed by combining ultrasonic testing technology with deep learning method.Finally,the intelligent monitoring system for structural damages during long-term use of steel recycled concrete composite structures is constructed based on BIM platform.This study provides a new method for monitoring and predicting the long-term performance of the steel reinforced recycled concrete composite structure.
