AECOM Bridge Instrumentation & Evaluation Lead, North America 
**Receive 1.0 Professional Development Hours**

Topic Description:
Bridge instrumentation and field testing/monitoring involves various types of sensing and data collection technologies, non-destructive testing/evaluation (NDT/E) techniques, as well as structural testing/monitoring methods. If planned and implemented properly, field instrumentation can provide information on bridge in-situ conditions and actual responses to specific loads, which would not be known otherwise. Applications of bridge instrumentation and field testing/monitoring include bridge load rating, fatigue life assessment, condition and defect assessment, problem diagnosis, and various types of structural performance evaluation. The ultimate goal is to support engineers and bridge owners for better decisions in bridge maintenance, weight restrictions, preservation, and replacement. 

This presentation will discuss several bridge instrumentation and field testing/monitoring methods through example projects. The methods will include diagnostic and proof load testing for bridge load rating, field measurement of stress range histograms for fatigue life assessment, the taut cable vibration measurement (TCVM) method for assessing existing tension in cables or P-T bars, and investigation of signs of distress for effective repair methods. The discussions will address instrumentation plans, data collection and processing methods, testing/monitoring results analysis, comparison with and calibration of analytical models, and finally and most importantly, decision support in bridge maintenance and preservation. 

Speaker Bio:
Dr. Ed Zhou, P.E., is AECOM’s Bridge Instrumentation & Evaluation Lead in North America, with 24 years of experience in field testing and non-destructive evaluation (NDE) of various types of bridge structures. Ed has evaluated over 100 bridges across the U.S., including many in Maryland, through field instrumentation, structural monitoring, load testing, non-destructive testing (NDT), and finite element analysis for the purposes of strength evaluation, fatigue life estimation, condition and defect assessment, performance problem diagnosis, and decision support in bridge maintenance, weight posting, preservation, and replacement.  

Ed earned his B.S. in Civil Engineering from Northern Jiaotong University in China, and M.S. and Ph.D. in Civil Engineering from Lehigh University. He has served in several national technical committees as: past chairman of ASCE Committee on Fatigue & Fracture; member of ASCE Committee on Methods of Monitoring Structural Performance; member of TRB Committee on Field Testing and Nondestructive Evaluation (NDE) of Transportation Structures; and member of AREMA Committee 15 Steel Structures and Committee 17 High Speed Rail Systems. Ed taught several graduate courses in bridge engineering as well as the undergraduate civil engineering capstone course Design and Synthesis at Johns Hopkins University between 2000 and 2015.
