Real-time Monitoring and Evaluation Algorithm of Civil Engineering Material Performance Based on Sensor

Real-time monitoring of the performance of civil engineering materials is an important part to ensure the quality and safety of the project. Sensor technology uses various sensors to monitor the properties of materials, such as temperature, humidity, stress, strain and pressure. These sensors can collect data in real time and transmit the data to the monitoring system for engineers to make analysis and decision. In this paper, the real-time monitoring and evaluation algorithm of civil engineering materials based on sensors is studied. Multiple FGS (Fiber Grating Sensor) are laid on the upper and lower surfaces of reinforced concrete structures to form a distributed measuring system to measure the strain changes of reinforced concrete structures during loading. In order to effectively evaluate the seismic resistance of frame structures, an anisotropic damage model of concrete under constant lateral pressure is established based on the actual size and reinforcement of members in China’s current seismic design code. The research results show that the measurement data of FGS has enough accuracy and good reliability. This method can not only quantitatively evaluate the seismic capacity of buildings, but also find the parts with insufficient seismic capacity, which provides a foundation for subsequent reinforcement.
