For characterization of fiber reinforced soil under static loading conditions, there is a wealth of literature. However, study on dynamic behaviour of fiber reinforced soil is very limited. Now earthquakes are occurring frequently around the world due to this the dynamic soil analysis has become important for all classes of geotechnical engineering problems. Through numerical simulation of triaxial specimens, the current study explores the behaviour of fiber reinforced cohesionless soil. The numerical model was validated using existing laboratory triaxial compression testing literature. The stress–strain response of fiber-reinforced sand has been investigated using static and cyclic triaxial testing, as well as other combinations of fiber contents. Fiber-reinforced sand is tested for bulk modulus, shear modulus, and damping values. Effects of fiber contents on static and dynamic stress–strain response of fiber reinforced soil are highlighted. It has been observed from results that, with an increasing in fiber content modulus of elasticity, bulk modulus and shear modulus value increases while damping coefficient decreases for the same. It is believed that the highlighted numerical approach will be an alternative to laboratory experiments to determine the dynamic properties of fiber reinforced soil.
