The aforementioned flexible steel stairway was instrumented using a local multi-channel network of accelerometers in September 2014. We installed on the stairway two 12 bit-nominal resolution, digital uniaxial accelerometers of the type KUOWA-PCD-30A, connected by cables and with 'common time' and 'common start' characteristics. The dominant modes of vibration of the stairway were computed by the 'modal response acceleration time history' methodology. In parallel, a detailed finite element method model of the stairway was formed and calibrated according to the ambient vibration results. We note that the identification procedure used for the dynamic characteristics of spatial structures yields results that can be used to develop a family of numerical models for the stairway ranging from the simple single-degree-of-freedom system to highly detailed finite element method models, while some useful information on the theoretical procedure for the identification of modal shapes is included herein.
