“…Krämer et al [23] presented DD tests on the widely documented Z24 Bridge in Switzerland. This three-span prestressed concrete box girder bridge became a benchmark structure [24]. Heywood et al [25] used strain and deflection data along with a code-based analysis to assess the fitness-for-purpose of four steel bridges, of various configurations, in Australia and New Zealand.…”

Many researchers in the field of civil structural health monitoring (SHM) have developed and tested their methods on simple to moderately complex laboratory structures such as beams, plates, frames, and trusses. Fieldwork has also been conducted by many researchers and practitioners on more complex operating bridges. Most laboratory structures do not adequately replicate the complexity of truss bridges. Informed by a brief review of the literature, this paper documents the design and proposed test plan of a structurally complex laboratory bridge model that has been specifically designed for the purpose of SHM research. Preliminary results have been presented in the companion paper. IntroductionThe structural complexity of operational bridges poses a significant challenge for structural health monitoring (SHM) researchers. Reference [1] highlights that a 'primary source of epistemic uncertainty [in structural identification] is related to the relatively high level of structural complexity typical of constructed systems,' (p. 406). Ciloglu [2] found that structural complexity contributes significantly to the uncertainty of structural identification by operational modal analysis (OMA). Aktan et al. [3] argue that the basic assumptions that enable system identification of structures do not hold true for more complex constructed systems, particularly in a climate with daily temperature fluctuations of more than 10°C where temperature and humidity can have a significant effect on the vibration characteristics of an operational structure.

“…During the project different kinds of damage had been introduced. As a benchmark example this bridge was also investigated during the EU COST F3 action ''Structural Dynamics'' [76][77][78]. A scenario of great practical relevance is the dangerous undercutting of a pier, a hardly detectable damage that frequently appears in reality.…”
