Finite-Element Modelling of Timber-Fibre Concrete Composite Floor in Fire
Result description
Timber-concrete composite structures are becoming very important because they are widely used as an effective method for refurbishment of existing timber floors and for floors of new multi-storey timber houses. New kind of such floor is that the usual reinforced concrete is replaced by steel fibre reinforced concrete (SFRC). One of the most important requirements of timber-fibre concrete composite is fire resistance. This paper presents 3D FE model developed to predict the thermal analysis of timber-fibre concrete composite floor in fire. All this modelling is done using a commercial programme Ansys 14. The results obtained in the numerical simulations are compared with results obtained from furnace test. Furnace test was performed on one full-size floor specimen at the Fire testing laboratory PAVUS in the Czech Republic. Floor specimen was 4,5 m long and 3 m wide, consisting of 60 mm fibre concrete topping on plywood formwork, connected to GL floor joists. It was subjected the standar
