Technical code for monitoring
of building and bridge structures
1 General provisions
1.0.1 In order to standardize the building and bridge structure monitoring technology and the corresponding analysis and early warning, to achieve advanced technology, reliable data and reasonable economy, this code is hereby formulated.
1.0.2 This code is applicable to the monitoring of engineering structures such as high-rise buildings and structures, long-span spaces, bridges and seismic isolation structures, as well as the monitoring of existing structures affected by the crossing construction.
1.0.3 Construction and bridge structure monitoring shall, in addition to complying with the provisions of this code, also comply with the relevant requirements of the current notational standards.
2 Terms and symbols
2.1 Terms
2.1.1 Structural monitoring
Frequent, continuous observation or measurement of the state of the structure. 2.1.2 Construction monitoring
Structural construction monitoring.
2.1.3 Post construction monitoring
Structural post construction monitoring.
2.1.4 Monitoring system
It is integrated by the software and hardware for the purposes of achieving a certain monitoring function, composed of the monitoring equipment.
2.1.5 Monitoring equipment
It refers to, in the monitoring system, the collective name of sensors, collectors and other hardware.
2.1.6 Transducer/sensor
An equipment or device that senses a given measurement results AND
transforms it into a usable output signal in accordance with certain principles, usually consisting of a sensing element and a conversion element.
2.1.7 Times of monitoring
Number of monitoring per unit time.
2.1.8 Precaution value for monitoring
It refers to, in order to ensure the safety or quality of the engineering structure and the surrounding environment, the warning value set for the monitoring amount indicating the possible abnormal or dangerous state of the monitoring object.
2.1.9 Monitoring system stability
