Laboratory testing of steel fibre reinforced shotcrete

Abstract

Uniaxial and triaxial compression tests on steel fibre reinforced shotcrete (SFRS) have been used to quantify the elastic-plastic response behaviour for both the peak and post-peak regions. The laboratory tests were conducted with a servo-controlled testing machine to obtain complete stress-strain curves. The test results include unconfined and triaxial compressive strengths, shear strengths and tensile strengths together with the elastic and plastic mechanical properties of SFRS. A method is also suggested for obtaining the plasticity parameters for non-linear modelling of SFRS.
