Large-scale public buildings have the characteristics of large investment, complex structure, long construction period, complex construction technology, and long service life. During the service period, under the influence of factors such as abnormal load, material aging, and component defects, the structure will gradually accumulate damage, thereby reducing the bearing capacity of the structure and the ability to resist natural disasters. In the event of catastrophic loads such as earthquakes and typhoons, or in recent years, the occasional wind-induced vibration, the resonance effect of the environmental vibration source and the natural frequency of the building structure, will cause extremely serious dangerous accidents, and it will be difficult to control and Evaluate. Real-time dynamic monitoring and diagnosis of the health status of building structures, timely detection of structural damage, prediction of possible dangers, and evaluation of the safety, reliability, durability and applicability of service structures have very important practical significance.
Building structural health monitoring is a scientific monitoring method without damage to building structures. The structural health monitoring process involves the use of periodically sampled sensor (smart structural diagnostics) arrays to obtain structural responses, the extraction of damage sensitive indicators, and the statistics of damage sensitive indicators Analysis to determine the current state of structural health, among other processes.
WITBEE® Wanbin® building structure health monitoring system deeply integrates technologies such as AIoT, 5/4G, Beidou satellite navigation, big data, and 3D visualization. Through sensing data such as intelligent structural diagnostics, environmental sensors, and video surveillance, it has multi-dimensional situational awareness, Features such as all-weather three-dimensional protection, full life cycle management, and intelligent monitoring and early warning. According to structural monitoring indicators such as horizontal displacement, settlement, inclination, vibration, acceleration, etc., as well as external conditions such as wind force and temperature, it can realize early warning of building structure safety and rapid assessment of health, effectively predict the change trend of building structure, and let managers anytime, anywhere Understand and view the operating status of buildings, strengthen the safety supervision of building structures, assist managers in making scientific decisions, reduce the occurrence of risk events, and ensure the safety of people's lives and property.
Monitoring object
Super high-rise buildings, long-span buildings
Main monitoring content
1. Displacement and settlement monitoring
By installing intelligent structural diagnostic devices (including Beidou) on the roof of the building and the main load-bearing structure, the displacement and settlement data of the building are monitored in real time, and a data simulation model is formed to provide a platform analysis for the stability of the building.
2. Tilt monitoring
By installing intelligent structural diagnostic devices on the main load-bearing structures in buildings, such as walls, columns, beams, etc., the inclination monitoring of supporting structures can be realized to maintain building safety.
3. Vibration monitoring
The surrounding buildings will affect the housing construction, such as the vibration of construction site, pipeline laying, etc., and the vibration of the earthquake will cause damage to the housing structure. Install intelligent structural diagnostic devices around the housing to monitor the vibration of the surrounding ground in real time and maintain the safety of housing construction. .
4. Environmental monitoring
It refers to the monitoring of building environment, climate and other factors. Environmental monitoring can obtain data through sensors such as temperature, humidity, wind speed, rainfall, and air pressure, and analyze the degree of influence and change trend of the data on the structure.
The purpose of building structural health monitoring is to detect potential structural problems early, and take corresponding repair and reinforcement measures to ensure the safety and reliability of buildings, improve the disaster resistance and service life of buildings, and protect people's lives and property. This technology plays an important role in the safe operation of urban lifelines, and will be more widely valued and applied in the steady development and construction of cities in the future.
