1General Provisions
1.011 This code is formulated to standardize the monitoring technology and the correspondingprecaution analysis to ensure advanced technologies, reliable data, and reasonable cost formonitoring of building and bridge structures.
1.0.2 This code applies to monitor. high-rise buildings and structures, long-span spatialstructures, bridge structures, isolated structures, and existing structures influenced by crossingconstruction.
1. 0. 3Monitoring of building and bridge structures shall meét "he requirements of this code andthe relevant current national standards.
2 Terms and Symbols
2.1 Terms
2.1.1 structural monitoringFrequently and continuously observing or measuring the structural state
2.1.2 construction monitoring
Structural monitoring during construction,
2.1.3 post construction monitoring
Structural monitoring during service life.
2.1.4 monitoring system
Software and hardware integration with certain monitoring functions composed of monitoring
equipment.
2.1.5monitoring equipment
General designation of hardware such as tfansducers/sensors, acquisition instruments, etc. ,
in the monitoring system.
2.1.6 transducer/sensorInstruments or devices be able to sense measured signals and convert them to usable outputsignals according to a specifie rule,and usually consisting of sensing and transduction elements.2.1.7times of monitoring
The number of monitoring times per unit time.
2.1.8 precaution value for monitoringThe alarming value of monitoring quantities indicates the possible abnormal or dangerous stateof the monitoring object, to ensure the safety or quality of engineering structures and the
surroundings safety.
Basic Requirements
3.1General Requirements
3.1.1Structural monitoring of buildings and bridges shall be divided into construcfion monitoringand post construction monitoring.
3.1.2Construction monitoring should be combined with mensuration, observation, inspection,and engineering control, Post construction monitoring should be carried out by using a monitoringsystem with automatic data acquisition.
3. 1.3Patrol inspection and system maintenance shall be carfied out during monitoring.3. 1. 4Construction monitoring should be considered in conjunction with post construction monitoring.3.1.5Before monitoring, the monitoring purpose shall be clarified according to the monitoringrequirements of all parties and design documents, The monitoring scheme shall be formulated incombination with factors such as engineering strietural characteristics, site and surrounding
environmental conditions.3. 1. 6 Monitoring requirements shall be put forward at the design stage for structures that need
to be monitored :
3. 1.7'The monitoring scheme of the following engineering structures shall be especially demonstrated:1 Class A or complcx Class B scismic protcetion classifieátion of high-risc buildings and
structures, long-span spatial structures.2 Extra-large and complex bridge structures.3Engineering structures that are resumed to construction or use through detection,treatment, and evaluation after a severe accident.
Engineering structures with complex monitoring schemes or need to be demonstrated.
