Abstract

Recently structural damage has been frequently observed in reinforced concrete bridges due to repeted ioads such as vehicular traffic and due to continual overloads by heavy trucks. Therefore. In this study, the static tests and the fatigue tests were performed on a series of SFRC(steel fibrous reinforced concrete) to investigate the fatigue behavior of SFRC varying with the steel fibrous contents. Through this test, the diagonal cracking loads, ultimate loads, deflections, strains of concrete and steel. On this basis, the crack growth and failure of SFRC beams were studied, and a model for S-N relationship of SFRC was proposed.
