This dataset provides the raw responses in Excel (in Volts) of microelectromechnical and piezo-electric accelerometers positioned on the structural model and equivalent shear beam (ESB) container used to conduct the centrifuge tests considered in ‘Tuned mass damper positioning effects on the seismic response of a soil-MDOF-structure system’ in the Journal of Earthquake Engineering. Fig. 4 in the accompanying research paper shows a layout of all instrument positions in the model. The calibration factors (g/V) of all accelerometers are provided below. Multiplication of the raw response (V) by the calibration factor (g/V) results in acceleration response (g).
