Abstract
AbstractThis study investigates the vibration characteristics of composite timber-concrete floor systems to provide a reliable benchmark for optimizing composite floor system designs. This paper uses the numerical and analytical methods for evaluation to support more detailed study results and to build a comprehensive model for future research. Through Strand7 and ABAQUS numerical finite element analysis, geometrical layout and beam material effects on the timber-concrete composite floor are thoroughly explored. Meanwhile, the analytical results are further compared with the analytical solution based on the Dunkerley method and AISC. Then 15 kinds of timber-concrete composite floor designs are simulated and numerically tested. It was found that the dimensions of the timber beams and their composition might affect the natural frequencies of the floors. On this basis, this paper proposes future design schemes to provide reliable suggestions for further research.
