British Columbia Smart Infrastructure Monitoring System (Bcsims)

Abstract eng:
The British Columbia Ministry of Transportation and Infrastructure and the University of British Columbia, Canada, have recently embarked on a program to instrument key structures to provide confirmation of seismic capacity, assist in focusing retrofit efforts, detect damage from any cause and provide rapid damage assessment of those structures following a seismic event. The instrumentation system installed at each structure is capable of remote configuration and can automatically upload data to a central server via the Internet. As part of this collaboration effective damage detection algorithms that provide reliable intelligence close to real time have been developed and implemented. This technology is used to i) detect, analyze and localize damage to structures; ii) transmit the data regarding these structures in real time via the internet; iii) display in animated and static web pages the data as appropriate for use by the Ministry and UBC. The alert systems and public access web pages can display real time seismic data from the BC Strong Motion Network to provide input for assessments by the Ministry of non-instrumented bridges. These systems may also provide other agencies, emergency responders and engineers with situational awareness. This Project will help transform the current practice of inspecting and evaluating all structures after an earthquake to a more rational and effective one that makes effective use of sensing technology with fast and efficient techniques for data analysis and interpretation. Inspections by the Ministry can then be focused and prioritized to maximize the effectiveness of scarce resources.
