Dynamic Behavior of the Composite Steel–Concrete Beam Floor Systems under Free and Forced Vibration

This paper aims to investigate the dynamic behavior of composite steel–concrete floor systems under both free and forced vibrations. A combination numerical analytical methods was comprehensively employed calibrate suggested solutions extend application accurate in future design purposes. Different commercial Finite Element Packages including ABAQUS/CAE Strand7 were precisely utilized. The obtained results from Simulations broadly compared with available international guidelines British Standard BS 6472 standard ISO 10137. first 10 active vibration modes different beam numerically investigated. concrete slabs by respecting designated various types secondary primary steel components examined. It found that lengths beams can considerably influence computed fundamental frequencies response factors simulated system. Based on carrying out an extensive parametrical study, further practical recommendations provide a reliable benchmark for structural designers.
