System‑identification techniques have been applied to model the dynamic behavior of structures, and existing literature on damage and reliability functions has been reviewed. The paper investigates how inspection and test data can be used to identify structural characteristics such as damage and reliability, formulates the general structural identification problem, and proposes a practical implementation. The methodology employs selected inspection and test results, including nondestructive and proof‑load tests, to identify structural characteristics.
In this paper, possibilities of identifying important engineering characteristics of the structures using selected inspection and test results are examined. Recently, methods of system identification have been used to obtain a set of differential equations or generalized impulse response functions for the representation of the dynamic behavior of a given structure. It is suggested herein that the characteristics to be thus identified can include such functions as the damage and reliability of the structure at the time of the test and inspection. The general problem of structural identification is formulated and considered. The literature on damage function and reliability functions of structures are reviewed and summarized. Possible applications of various testing procedures including nondestructive and proof-load tests for structural identification purposes are also considered. Finally, the potentially practical implementation of such a methodology is suggested.
