GALLO-ARCINIEGAS, Lina P; GONZALEZ PENUELA, Giovanni  e  CARRILLO LEON, Julián. BEHAVIOR OF ZP-306 STEEL FIBER REINFORCED CONCRETE SUBJECTED TO COMPRESSIVE STRESSES. Cienc. Ing. Neogranad. [online]. 2013, vol.23, n.1, pp.117-133. ISSN 0124-8170.

ABSTRACT In Colombia, the use of steel fiber reinforced concrete (SFRC) is lacking because there are not enough experimental evidence and regulatory requirements on that subject in the country. This paper shows the results of an experimental and analytical researchon behavior of SFRC made of ZP-306 fibers, subjected to compressive stresses. The study involves the review and discussion of models available in the literature, as well as anexperimental program that included the test of 48 specimens. From a regression analysis of the measured data, equations are proposed to estimate the main mechanical properties of the SFRC, such as compressive strength, modulus of elasticity and Poisson's ratio. The equations correlate the mechanical properties with the main characteristics of steel fibers, such as content and aspect ratio.

Palavras-chave : Steel fiber reinforced concrete; compression; modulus of elasticity; Poisson's ratio; fiber content.
