Urban safety network for long-term structural health monitoring of buildings using convolutional neural network

Oh, Byung Kwan / Park, Hyo Seon

Abstract Structural response recovery and prediction technologies are required for long-term structural health monitoring (SHM). In this study, a structural response prediction method was proposed to evaluate the long-term safety of structures in which SHM system failure occurred by constructing a safety network of buildings in a given region. In this method, the correlation is defined by machine learning between the dynamic structural response of nearby buildings that are under the same load effects. Furthermore, a convolutional neural network was introduced in which the structural response correlation between two nearby buildings in a region is defined as a safety network. The safety network can be individually applied to multiple buildings, resulting in multiple networks that can be expanded to construct an urban safety network. To examine the applicability of the proposed technique, a safety network was constructed between two nearby buildings to predict the structural response of the target building.

Highlights • A safety network of buildings in a region is proposed. • In the network, correlation of structural responses of buildings is defined. • The correlation is used to predict structural responses of the nearby building. • For multiple buildings, the method can be expanded to urban safety network.
