Dynamic Properties of Human Hair Fiber–Reinforced Yamuna Sand

CODEN: JTEVAB

Abstract

A series of drained cyclic triaxial tests was conducted to examine the behavior of sand reinforced with human hair fiber of random lengths subjected to cyclic loading. Experiments were conducted at two different relative densities (i.e., 50 and 80 %) with varying fiber content (0.25 to 1.0 %). Factors affecting the cyclic behavior, such as relative density, fiber content, load cycles, and shear strain amplitude, were examined and discussed in this article. Shear modulus and damping ratio evaluated for all the tests indicate that the maximum increase in shear modulus of reinforced sand is observed under medium shear strains and at 0.5 % fiber inclusion for 80 % relative density. However, the fiber inclusion seems ineffective with the sand at 50 % relative density. The damping ratio of reinforced and unreinforced sand did not show a marked variation except for fiber content more than optimum.
