Abstract: 
The constitutive properties of structural materials are essential for modeling structural response for analysis, evaluation, and design. This is particularly true for the tensile properties of fiber reinforced concrete should its contribution be considered in the design of structural concrete members. This short paper summarizes a chapter of a draft document currently under preparation by ACI Committee 544, Fiber Reinforced Concrete, on the Measurements of Properties of Fiber Reinforced Concrete; in particular, Chapter 3, Tensile Properties, is addressed. Following a simple classification of the behavior of FRC composites as either tension strain-hardening or strain-softening, the types of tensile stress-strain or stresselongation response that can be experimentally obtained as well as the key elements of each response are explained. Several types of specimens, their preferred size, and the loading conditions are described. Some recommendation is provided for the measurements of strains and crack opening.
