The development of successful SHM methods generally depends on two key factors; sensing technology and the associated signal analysis and interpretation algorithms. A structure’s monitoring is essential, as unlike a human system, a structure cannot adapt to changes on its own. The Wind and Structural Health Monitoring System is a sophisticated bridge monitoring system, costing US$1.3 million, used by the Hong Kong Highways Department to ensure road user comfort and safety of the Tsing Ma, Ting Kau, Kap Shui Mun and Stonecutters bridges. Structural health monitoring (SHM) is a process of assessing the health of a structure through a smart and automatic monitoring system. For example, so many factors can cause a steel structure to lose its stiffness if we do not take necessary actions. However, studies show that it is difficult to analyze the structural condition of a structure by only visual inspection. Our specialists will assist you in selecting the necessary system components for your particular task. ZETLAB Company is ready to provide you with a turn-key system, design and working documentation, installation supervision, start-up and commissioning works. Periodic measurement by an array of sensors; 2. The sensing component of the SHM system includes the selection of sensor types, their number, and location. Charge amplifiers, coupling amplifiers How Global Seismic Data collects its data: GSD’s strategically-located sensors constantly monitor a building’s movement and behaviour. For example, a global monitoring approach has to be chosen when accessibility to specific parts of the structure is impossible. Structural Health Monitoring publishes peer-reviewed papers on technical investigations of structural health monitoring methods and technologies with an emphasis on balanced studies containing both theoretical and experimental aspects. An ageing structure incurs more cost with time, and this has become an ongoing concern. Leaflet in PDF format “Structural health monitoring system (SHM)”, Building tilt and bearing elements displacement control, Natural oscillations and damping ratio control. Among the additional advantages of the SHM system, one should mention the possibility of integrating third-party transducers into the structure of measuring lines. The measured data needs to be transmitted by wired or wireless transmission networks. Currently, the monitoring of existing structures involves scheduled-maintenance and visual inspection. SCADA ZETVIEW The case of a structural system is no different. The data acquisition component involves selecting the excitation methods, signal conditioning, and data acquisition hardware. All Rights Reserved. An SHM system typically consists of many vital components, including sensors, data acquisition, data transmission, data processing, data management, health evaluation, and decision making. STRUCTURAL HEALTH MONITORING SYSTEM (SHMS) 06 November 2020 17:19. Structural Health Monitoring (SHM) is the process of implementing a damage detection and characterization strategy for engineering structures, in order to maximize safety and minimize maintenance cost. Conversion of Shipping Containers into Homes, How to do Architectural Design and Engineering work in Coronavirus Pandemic, Scheduling of inspection on an “as needed” basis. Structural health monitoring system can be used at any types of engineering structures: high structures, dams, and dikes, bridges, tunnels, large sports facilities, dilapidated structures, etc. However, the application of SHM technology in structural engineering is still growing. Products for electric circuits control Structural health monitoring alleviates this concern. You can use the calculator below to simplify the design process. Seismic Recording Systems Structural Health Monitoring system is a set of subsystems that are used for the controlled parameters monitoring in real-time mode. Structural Health Monitoring system is a set of subsystems that are used for the controlled parameters monitoring in real-time mode. Scope includes but is not limited to: vibration, wave propagation and multi-physics methods for damage assessment; structural health monitoring sensor … When developing a monitoring system used for control of various facilities using ZETLAB measuring instruments, the Customer can select a channel for data transfer from the measuring lines to the data server. SHM finds application in many engineering industries, such as aerospace and structural engineering. Structural identification; 3. © 2020 Meee Design Services. Structural health monitoring (SHM) system is a method of evaluating and monitoring structural health. For a structural health monitoring system to be compelling, it must be cost-effective and guarantee safety. A structural engineer, when designing a structure, ensures the structures must be able to withstand all possible loads. The two categories of SHM strategies are global and local. So, someone must monitor a structure to keep track of changes in the structural properties of the structure. How Structural Health Monitoring System (SHMS) Works. Interface converters Structural health monitoring (SHM) refers to an array of connected sensors to collect and analyze data, at every moment during the service life of the structure. Should you have any difficulties with selecting necessary components for your system, fill in the questionnaire and send it to zetlab@zetlab.com. Studies show that the United States utilizes way over $200 billion every year on plant equipment and structures maintenance. We monitor operations to ensure we are aware of the effect of time on the system and to be ready for any future changes. While SHM systems might vary in their architecture and deployment, they all encompasses four distinct subsets (Chang, 2003): 1. Structural health monitoring system (SHM) allows to timely detect ground base bearing capacity change as well as to reveal changes of structural elements and to inform the monitoring service of critical changes in the bearing structures parameters. Structural health monitoring technology can improve the design and management of engineering structures in many ways, a few of which are; Admittedly, Structural health monitoring ensures that a structure’s health is properly monitored. Allowing informed decision around seismic events or degradation over time. Thus, saving cost. Even after construction, structures face external loads, and with time the structure’s ability to withstand these loads deteriorate and may result in structural damage. Seismic It has been widely applied in various engineering sectors due to its ability to respond to adverse structural changes, improving structural reliability and life cycle management. +7 499 116-70-69 Shaker control systems Each of these components is equally important in assessing the health state of a civil structure. Congo, Democratic Republic Of (Was Zaire), Macedonia, The Former Yugoslav Republic Of, South Georgia And The South Sandwich Islands. DOWNLOAD ZETLAB SOFTWARE, FFT Spectrum Analyzers Hence, saving the cost of unneeded maintenance on the one hand and minimizing impromptu maintenance, on the other hand. Intelligent Sensors and Controllers Real-time Structural Health Monitoring System Using Internet of Things and Cloud Computing H. Chang1 and T. Lin2 ABSTRACT Real-time monitoring on various structural behaviors, particularly displacement and acceleration, serves important and valuable information for people; for example, they can be used for active control or damage warning. Depending on Customer’s requirements, the Structural Health Monitoring System may include all types of the monitoring systems or a particular task-specific set of the monitoring systems. However, its benefits show that it is viable and should be fully implemented in the structural engineering industry. Structural health monitoring has multiple applications. Selection of the required cable type to be used for measuring lines should be based on the total length of the measuring line, power supply source used and the number of digital transducers in the measuring line.
