title: Research data supporting "Tuned mass damper effects on the response of multi-storied structures observed in geotechnical centrifuge tests"

description: This dataset provides the raw responses in Excel (in Volts) of microelectromechnical and piezo-electric accelerometers positioned on the structural model or equivalent shear beam (ESB) container used to conduct the centrifuge tests considered in ‘Tuned mass damper effects on the response of multi-storied structures observed in geotechnical centrifuge tests’ (accepted on 23rd June 2015 for publication in Soil Dynamics and Earthquake Engineering). Fig. 2 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). Loose sand Instrument (-) / Calibration Factor (g/V) M1/51.88 (first floor response) M2/53.05 (second floor response) P1/8.80 (ESB input) Dense-loose-dense sand Instrument (-) / Calibration Factor (g/V) M1/56.82 (first floor response) M2/43.43 (second floor response) P1/6.61 (ESB input) The raw data was recorded in centrifuge tests conducted with the Turner beam centrifuge facilities available at the Schofield Centre (High Cross, Madingley Road, Cambridge, CB3 0EL) between 10/06/2013 and 27/09/2013. Below is a list of the file names of the instrument response recordings, what they have recorded and which figure(s) in the accompanying research paper they relate to: Figure 3: - 1st floor response to 1.2→0 Hz sweep for loose sand, no TMD (D.xlsx, column 2) [M1/51.88] - 2nd floor response to 1.2→0 Hz sweep for loose sand, no TMD (D.xlsx, column 3) [M2/53.05] Figures 5 & 6: - 1st floor response to 0.6 Hz earthquake for loose sand, no TMD (A.xlsx, column 2) [M1/51.88] - 1st floor response to 0.6 Hz earthquake for dense-loose-dense sand, no TMD (H.xlsx, column 2) [M1/56.82] - ESB input to 0.6 Hz earthquake for dense-loose-dense sand, no TMD (G.xlsx, column 2) [P1/6.61] Figures 7 & 8: - 2nd floor response to 0.6 Hz earthquake for loose sand, no TMD (A.xlsx, column 3) [M2/53.05] - 2nd floor response to 0.9 Hz earthquake for loose sand, no TMD (C.xlsx, column 2) [M2/53.05] - 2nd floor response to 0.9 Hz earthquake for loose sand, TMD de-tuned to 0.5 Hz (E.xlsx, column 2) [M2/53.05] - ESB input to 0.6 Hz earthquake for loose sand (B.xlsx, column 2) [P1/8.80] Figures 9 & 10: - 2nd floor response to 0.6 Hz earthquake for dense-loose-dense sand, no TMD (H.xlsx, column 3) [M2/43.43] - 2nd floor response to 0.7 Hz earthquake for dense-loose-dense sand, no TMD (I.xlsx, column 2) [M2/43.43] - 2nd floor response to 0.7 Hz earthquake for dense-loose-dense sand, TMD de-tuned to 0.7 Hz (N.xlsx, column 2) [M2/43.43] - 2nd floor response to 0.7 Hz earthquake for dense-loose-dense sand, TMD tuned to 0.766 Hz (P.xlsx, column 2) [M2/43.43] - ESB input to 0.7 Hz earthquake for dense-loose-dense sand (M.xlsx, column 2) [P1/6.61] Figure 11: - 2nd floor response to 1.2→0 Hz sweep for loose sand, no TMD (D.xlsx, column 3) [M2/53.05] - 2nd floor response to 1.2→0 Hz sweep for loose sand, TMD de-tuned to 0.5 Hz (F.xlsx, column 2) [M2/53.05] Figures 12-13: - ESB input to 1.2→0 Hz sweep for dense-loose-dense sand (Q.xlsx, column 2) [P1/6.61] - 2nd floor response to 1.2→0 Hz sweep for dense-loose-dense sand, no TMD (K.xlsx, column 2) [M2/43.43] - 2nd floor response to 1.2→0 Hz sweep for dense-loose-dense sand, TMD de-tuned to 0.7 Hz (O.xlsx, column 2) [M2/43.43] - 2nd floor response to 1.2→0 Hz sweep for dense-loose-dense sand, TMD tuned to 0.766 Hz (R.xlsx, column 2) [M2/43.43] Figure 14: - Harmonic wavelet transform of 2nd storey response for dense sand (L.xlsx, column 2) [M2/43.43] Figure 15: - Harmonic wavelet transform of ESB input for dense sand (J.xlsx, column 2) [P1/6.61]
