New System of Monitoring of a Condition of Cracks of Small Reinforced Concrete Bridge Constructions

Abstract

The paper deals with the monitoring of the technical condition of bridges and description of the authors' remote system for monitoring crack opening in bridges allowing to take real-time measurements and to automate process of data transmission by means of a wireless communication. The short review and the analysis of the available devices for monitoring of the technical condition of building constructions is given. This system offered by authors is based on the crack-width- growth sensor which is protected by an invention patent. The paper presents a diagram of this device and its operation principle and conditions as well as technical parameters. Details of the processing system and the analysis of the obtained data on the inspection object are provided. The scope of the remote supervision system for the disclosure of cracks in bridge constructions is described.
