Steel fibre reinforcement is being increasingly considered as a profitable alternative to the traditional welded steel mesh for secondary load bearing mechanisms, such as the transversal bending of precast roof elements. An experimental investigation was carried out on HPSFRC to assess the mechanical behaviour, when subjected to high temperature. The mechanical behaviour was identified by means of bending tests, after a thermal cycle, and also for hot specimens after a fast extraction from the oven. The results were adopted to reproduce the fire behaviour of bent plates exposed to a standard fire curve.

Abstract
Steel fibre reinforcement is being increasingly considered as a profitable alternative to the traditional welded steel mesh for secondary load bearing mechanisms, such as the transversal bending of precast roof elements. An experimental investigation was carried out on HPSFRC to assess the mechanical behaviour, when subjected to high temperature. The mechanical behaviour was identified by means of bending tests, after a thermal cycle, and also for hot specimens after a fast extraction from the oven. The results were adopted to reproduce the fire behaviour of bent plates exposed to a standard fire curve.File in questo prodotto:
