Sand is a granular material widely used in civil engineering, particularly in construction and geotechnical applications. Understanding its dynamic properties is critical for forecasting soil behavior during earthquakes, landslides, and other geotechnical occurrences. A series of experiments are conducted by using on a biaxial shake table, which allows for precise control of the frequency, amplitude, and direction of shaking. The experiments are conducted for various input frequencies (2, 3 and 4 Hz), and accelerations (0.15, 0.2 and 0.25g) keeping the relative density of sand constant to study its effect on dynamic properties. The effect of Coir Geotextile on acceleration amplification at top of the sand setup and surface settlements are observed and compared. The results gave valuable insights into the behavior of sand under dynamic loading conditions. This information can be used to improve the design and construction of civil engineering structures, such as buildings, bridges, and retaining walls, to ensure their safety and stability during seismic events and other geotechnical hazards.
