TEMPERATURE AND LOADING LEVEL EFFECT ON THE LONG-TERM BEHAVIOUR OF MSFRC AND SFRC

This paper describes the results of an experimental campaign aimed at investigating the long-term behaviour of cracked SFRC and MSFRC beams. In particular it illustrates, the effects of temperature and loading level on the behaviour (in terms of crack opening and deflection) of four beams: two beams contained two different dosages of steel fibres and the remaining beams two different dosages of macro synthetic fibres. The tests showed large differences in the long-term behaviour of the different types of FRC and suggested that MSFRC may be more sensitive to loading level and temperature than SFRC.
