Structural Health Monitoring (SHM) of Ageing Infrastructures in Bahrain

摘要

There is a crucial need to investigate and monitor the situation of the existing infrastructures. Structural Health Monitoring (SHM) approach can be used to collect data from the ageing structures using non-destructive testing as well as sensors. This will provide some indications when there are some defects. The sensor system will continuously update the data about the current conditions of a structure including the detection of changes in the properties of materials related to degradation, such as corrosion of steel and fatigue cracks. SHM can be used for pre-emptive maintenance and structural wellbeing information for huge and complex structures such as buildings, bridges and towers. Recently, computerized systems have been used to monitor the aging infrastructure for its safe and economical operation. The current study will focus on identifying the ageing infrastructures in Bahrain, assessment of their current loading scenarios compared with the original design, and develop SHM system by a centralized monitoring system. This will include instrumentation, data acquisition, communication system and procedure for diagnosis of infrastructural health.
