Typical one-way composite steel/concrete floor systems are common in steel-framed buildings. These flooring systems are heavy and result in large gravity loads, high inertial forces, and assumptions are made about the occupancy and usage needs that must last through the life of the structure. To address these disadvantages, a lightweight rapidly constructible and reconfigurable modular steel floor (RCRMSF) system is developed with two-way action using cold-formed steel materials. In order to address the lack of knowledge in regards to the design of RCRMSFs, a vibration serviceability design assessment has been formulated based on current design standards and recommendations. A finite element analysis (FEA) parametric study has been carried out in Abaqus FEA software considering different channel and plate thickness and configurations. The results of the design assessment and FEA study show that both methods provide agreeable results. Based on the FEA, RCRMSF systems are suitable to resist vibrations for typical office structures with proper configuration.
