Qualitative health monitoring and incipient damage inspection/evaluation
… which can be implemented for real-time damage evaluation of complex structures, is investigated. The basic principle of the technique is to monitor the structure's mechanical impedance which will be changed with the presence of damage. The mechanical impedance variations are monitored by …

Applications of optical fiber sensors with thick metal coatings
… about the strain state of the sensor. A post-damage inspection fiber optic sensor design which employs a thick metal coating to retain information regarding the strain history of a sensor is demonstrated. Additionally demonstrated is a corrosion sensing technique which exploits the residual …

Mobile hyperspectral imaging for structural damage detection
Numerous optical-imaging and machine-vision based inspection methods are found that aim to replace visual and human-based inspection with an automated or a highly efficient procedure. However, these machine-vision systems have not been entirely endorsed by civil engineers towards deploying these …

Semantic Segmentation and 3D Reconstruction of Concrete Cracks
Damage inspection of concrete structures is necessary to prevent disasters and ensure the safety of premises such as buildings, sidewalks, dams and bridges. Cracks are among the most prominent damages in such structures. In this research, a computer vision and machine learning-based solution for …

Design of Structural Stand for High-Precision Optics Microscopy
… dozens of large optics, which require offline damage inspection using large, raster-scanning microscopes. The primary microscope used to measure and characterize the optical damage sites has a precision level of 1 µm. Mounted in a class 100 clean room with a raised tile floor, the microscope is …

Parametric Soil-Structure Modeling for Rapid Climatic Disaster Response
… In the context of structural and geotechnical damage inspection, it calls for efficient tools that can analyze coastal structures that take a system modeling approach. Such a system approach should consider structuresthat are subjected to a combination of extreme forces and changes of boundary …

A Machine Learning and Computer Vision Framework for Damage Characterization and Structural Behavior Prediction
… to relate surface (and limited subsurface) damage observations to quantitative damage and load levels in structural components. In particular, image processing and machine learning regression techniques have been used to build predictive models capable of estimating internal loads (e.g., …
