The effectiveness of mode-shape-based damage location methods is investigated, with specific regards to their application to the assessment of civil structures.
Despite the recent increase in the scientific literature dealing with new damage identification methods, it is commonly recognized that only methods that utilise mode-shape information are proven to be effective in practical applications to civil structures.
Nevertheless, the experiment pointed out some issues concerning the practical application of these techniques to civil structures.

engineers’ sufficient attention.
The longest predicted service period of concretes in this survey is merely 39.1 years when the carbonation depth reaches 25 mm, which is the common concrete cover thickness of reinforced structures in civil engineering; and the shortest is only 8.7 years, that is CO2 could straightforwardly penetrate into concrete and the concrete cover has little effect on protecting the reinforced steels.

Introduction The damage or collapse of civil engineering structures under strong motions and strong winds is direct cause of disaster and loss, accordingly, seismic and wind resistance is all along the hotspots in civil engineering.
Accordingly, it is widely used in signal analysis domain, and it is also concerned in civil engineering field recently years[1-6].
Evolutionary spectra proposed by Priestley[9,10] has been paying great attention in civil engineering for it’s explicit physical meaning.
First, methods describing time-frequency characteristics are not unified, and it is not convenient to be further applied in engineering.

The determination of the blast protection level of civil engineering buildings components against explosive effects represents a topic of crucial importance, in current practice.
Some essential requirements, for numerical approaches as well as for experimental studies, are given by [16, 17] and presented further on. 3.2 General Considerations about Numerical Tools At least two main methods are emerging as engineering tools for civil engineers: discretized numerical methods and engineering toolboxes.
