Project Description
This PhD project will investigate the influence of optimum effectiveness of construction parameters and level of fixity to obtain satisfactory vibrational performance timber floors built with long spanned I-joists. Laboratory-based experimental work and non-linear numerical based Finite Element study will be conducted to attain the objective. In laboratory investigation, a series of floors with different spans will be tested under static and dynamic loads. Influence of geometric arrangements and rigidity of construction parameters to joists will be studied. These tests will assist in looking at how modification in construction parameters can enhance the transverse stiffness and to what extent this influences on static deflection and natural frequencies of floors. Based on test results, analytical and numerical models will be developed to investigate further on the vibrational performance of timber floors. The results from experimental and numerical study will be used to develop a generalised approach that can be used in predictive models to calculate structural response of timber floors to static and dynamic loading conditions and can be incorporated into a design procedure for controlling vibration in residential timber floors.
This research will provide an in-depth understanding of vibrational performance and user comfort of residential timber floors built with engineered joists. This could be a valuable contribution in timber structures, especially, for industry and for design codes
