    Abstract

    This research describes the results of an experimental investigation designed to correlate the tensile and bending response of Ultra High Performance Fibre Reinforced Concrete (UHPFRC). The test program included several parameters, among which the same UHPFRC blinded straight steel fibres 13mm long with different fibre contents 2, 4 and 6%, and 6 different sizes. This investigation has compared the results of flexural tensile test (three point bending test TPBT and four point bending tests FPBT) against direct tensile test (DTT). As a result, equivalent bending strength out of the TPBT and FPBT were clearly higher than those calculated through DTT, the strength ratios at the elastic limit were 1:2.68:1.75 for the 2%. It has also been found that the equivalent bending strength increases as the size decreases, proving the size dependency of UHPFRC which have been partly corrected using an approach recommended from (AFGC, (2013)).
