Title

An Integrated View For Structural Identification Of Civil Infrastructure Systems: An Overview Of A Collaborative Asce Committee Effort

Abstract

Structural Identification (St-Id) has been widely applied to civil infrastructure systems similar based on the developments in System Identification (Sys-Id), which is very simply establishing relationships between inputs and outputs to a system. Sys-Id started in electrical engineering by taking advantage of control theory. Recently, Sys-Id has been implemented in almost all engineering disciplines, mathematics, physics as well as social sciences. Taking advantage of previous work in Sys-Id, St-Id of civil infrastructure systems has experienced major research and developments since the 70s especially with the advances in computational power and sensing technologies. Due to the multidisciplinary and broad nature of St-Id, a wide variety of theory and applications such as ranging from geometric modeling to parameter identification to model updating can be found in the literature. Consequently, parts and pieces of these developments in St-Id have been employed for research studies or for real life problems with advanced engineering requirements. By recognizing the importance of St-Id, ASCE-SEI Performance of Structures Track established a technical committee on "Structural Identification (St-Id) of Constructed Systems" in 2005. One of the objectives of the committee is to develop guidelines for reliable field-calibrated analytical modeling and characterization of existing constructed systems to fill the gap between theory and practice by utilizing various methods and technologies for St-Id. The committee established six critical steps for conducting a complete and successful St-ID for constructed facilities. These steps are: 1) Establishing the drivers for St-ID, 2) A-Priori Modeling, 3) Experimentation, 4) Processing data for parameter ID and interpretation, 5) Evaluation of model errors and 6) Utilization for decision making. This paper summarizes these steps, the fundamental knowledge areas and their relation to concepts presented in the Committee Report. As a result, this paper provides detailed information about the collective efforts of the committee for developing St-ID guidelines for constructed facilities. © 2010 American Society of Civil Engineers.
