Summary Short steel fibers have long been incorporated to cement-based materials to improve their low tensile strength and low energy consumption capability, which leads to the steel fiber reinforced cementitious composites (SFRC). However, the conventional fiber volume fraction (V-f) of 1-2\% cannot increase the tensile streIlg-th of the composites significantly. This has driven investigators towards the development of high performance SFRC using higher fiber volume fractions. The paper reports our experimental investigations of the uniaxial tensile behavior of SFRCs with V-f varying from 2-8\%. The preliminary results indicate that strain hardening response can be achieved for the composites reinforced with various steel fibers when the V-f reaches a threshold value. However, their overall performance varies, mainly depending on the properties of the fibers and the fiber volume fractions.
