Compression Characteristics and Structural Beam Design Analysis of Steel Fiber Reinforced Concrete.

摘要

The report studies the effect of steel fibers on the static compression strength of concrete and mortar. Using 6 x 12in., 4 x 8in.,and 3 x 6in. cylinders, 180tests were conducted on three different mixes:sand, 3/8in. maximum aggregate,and 3/4in. maximum aggregate. Data that indicate the strength of the fiber concrete may vary inversely with the sand content. Values for Young's modulus and Poisson's ratio for the various fiber percentages are also given. It is suggested that fibers can be used economically in flexural members. A cost comparison of a reinforced concrete beam with stirrups versus a reinforced concrete beam with fibers with no stirrups is presented. (Modified author abstract)
