Vibration-Based Damage Detection of a Steel-Concrete Composite Slab Using Non-Model-Based and Model-Based Methods

Figure 6

Measured displacement and strain on the structure: (a) measured vertical displacement at the middle span of girder 2; (b) measured steel strain at the 1/4 and 1/2 span locations of girder 1, 2, and 3; (c) measured concrete strain on the bottom surface at the 1/2 span location.
