Laminated rubber bearings may exhibit rupture damage due to factors such as temperature variations and seismic activity, which can reduce their isolation performance. Current detection methods, including human‐vision inspection computer‐vision inspection, have certain limitations in accurately assessing the degree of damage. This study attempts combine piezoelectric‐based active sensing method with a machine learning algorithm detect laminated bearings. A series varying degrees were...
Sparse regularization methods have been extensively used in impact force identification to accurately determine locations and the time history of forces. It is known that accuracy localization can be significantly improved by increasing location potential action, which also leads a significant increase dimensionality transfer matrix. Consequently, this reduces computational efficiency substantially makes it difficult achieve online monitoring. Considering non-convex sparse method, such as...
In bridge engineering, void damage in rubber bearings refers to the phenomenon where gaps occur between bearing and structure due factors such as aging, overloading, earthquakes. Void can lead abnormal stress distribution, deformation failure, uneven load transfer, thereby affecting overall stability safety of bridge. Consequently, long-term monitoring is essential. However, methods manual inspection computer vision have disadvantages, including high costs, lengthy processes, limited scope....
Base-isolated structures can effectively control structural response, of which rubber bearings are key components. To ensure the proper functioning bearings, it is important to accurately detect their state. In previous studies, a smart bearing has been proposed monitor axial pressure, shear deformation, and rupture damage bearings. However, owing small dataset limited ability prediction model, two problems exist in research: (1) cannot be detected simultaneously (2) detection accuracy not...
