This study collected data on the performance of shallow steel-timber composite floor structure, Nordic system. Specially focusing on the integration of cross-laminated timber (CLT) slabs and the used asymmetric welded box beams (WQ-beams) to investigate the effect of the composite action. To explore the Nordic system's potential in enhancing structural efficiency, six full-scale tests assessed bending and vibration performance, and a number of Push-out tests the connection properties. Data collection on bending tests involved measuring jack forces, deflections, strains, and slip between members, and for vibration tests deflection and acceleration during dynamic loading. Push-out tests evaluated the shear performance of wood screws by measuring defection and jack forces. The tests were meticulously conducted by a same skilled team at Tampere University, utilising. The resulting dataset, presented in Excel format with illustrative graphs and pictures, offers valuable insights for construction firms, product developers, and researchers. It serves as a comprehensive reference for validating finite element models and developing advanced design standards for shallow steel-timber composite structures. Series information Datasets are deviated into three main categories: Full-scale Push-out Vibration Each file includes test-specific Excel documents, graphs, and photographs that document specimen behaviour before, during, and after testing. These Excel documents contain both raw and organised data from individual tests, such as bending, or groups of tests, including vibration and push-out. For vibration and push-out tests, graphs are incorporated within the Excel files. Due to the extensive data from full-scale tests, this information is processed into a visual format using Python code. In every instance, the raw data is directly sourced from the recording device and subsequently converted into a more comprehensive format for analysis. Specifics dimensions of the test specimens are shown in Appendix A, showcasing all assembly drawings utilised for ordering and constructing the test specimens.
