The most efficient tools in real monitoring system is acoustic emission (AE). This technique can be used to identify the damage classifications in RC structure. This research paper will mainly focus on the utilization of signal strength and Absolute energy (AE signal) in determining on the damage quantification for RC beam subjected to cyclic load test. The beam specimens size (150 X 250 X 1900) mm were prepared in the laboratory and tested with the four point bending test using cyclic loading together with acoustic emission monitoring system. The results showed that the analysis of AE data parameters is capable of determining the damage classification in concrete structures and the data corresponded to the visual observations during the increased loading cycle.

Durability Of Concrete

Purpose This study aims to explore the effect of corrosion monitoring technology for ensuring concrete structure safety. Design/methodology/approach A new monitoring system scheme with unattended operation to evaluate the durability of concrete structures is presented, which includes four components, namely, a multi-function embedded sensor, a microprocessor data collecting module, a system data analysis and storage module, and a remote server module. Findings The system carries out monitoring of chloride ion concentration and pH in concrete, corrosion current density and of the self-corrosion potential of the reinforcing steel bar. Originality/value This system provides real-time, online, lossless monitoring for concrete structures.

Remote Monitoring System

A wireless remote monitoring sensor network for durability of large concrete structures is designed and studied in the case that traditional parameters monitoring and durability evaluation methods are willing to promote to meet modern requirements. As traditional monitoring methods of concrete structure focus on the structural parameters while missed the research on durability of the structures, a Internet of Things (IOT) system of durability monitoring is designed to optimize and develop. By deploy sensor nodes for durability monitoring system based on ZigBee wireless network and GPRS remote data transmission, the durability sensor data collected can be send to the monitoring and evaluation computer information system based on data fusion to finish intelligent analysis, evaluation and early warning. In this way, the system conquered the problems that high maintenance cost, early deterioration of structural performance and shorten useful life, contributed to the structural safety of large-scale concrete works and take action to maintain normal operations in time. This meets the requirements of China's economic sustainable development, so it has important social significance and economic values.
