Shake-table test of a full-scale three-level cold-formed steel storage rack: raw data, processed data and analysis scripts

Shake-table test of a full-scale three-level cold-formed steel storage rack — raw data, processed data and analysis scripts What this record contains A full-scale three-level cold-formed steel storage rack module, produced by SKAT KART SRL (Romania), was tested on the ANCO shake table of the Gheorghe Asachi Technical University of Iași in March 2024. The rack carried 1375 kg of lead slabs on wooden pallets at its middle level. Two kinds of test are covered: six sine-beat runs of increasing intensity at a nominal 1 Hz, in the down-aisle (longitudinal) direction, recorded with four triaxial accelerometers and four laser displacement transducers; free-vibration tests, produced by short blows with a rubber hammer, recorded before the runs (28 March 2024) and after them (29 March 2024). The record contains the unmodified acquisition exports, the analysis windows, the processed results that appear in the paper, the scripts that produce them, and the source data of every figure.
