Abstract

There are numerous Structural identification (StrId) methods and techniques. The purpose of StrId in the civil infrastructure arena include: a) design validation of new structures, b) condition assessment of existing structures, c) analytical model updating of existing and new structures, and d) damage identification (DmId) of existing structures. Many StrId researchers utilized StrId methods for DmId. However, not all StrId methods are suited for DmId and not all damages are possible to be identified by popular StrId methods. This paper investigates the relationship between StrId methods and DmId. We investigate which StrId method is suited for DmId for the type of damages that may affect civil infrastructure. It will be shown that some damages can be identified by StrId methods, while some other damages need specific methods that are not within the conventional realm of StrId methods. Some guidelines for choosing StrId methods that are appropriate for DmId are given.
