Currently dynamic loading and its effects on foundation is quite a hot topic in the field of geotechnical engineering which occurred due to vibration effect on soil, and it is quite challenging to observe. This study was performed on the Resonant column equipment accompanied by the software Dynator. The usage of software needs a proper understanding and its effects on the testing properties of soil. The previous studies of dynamically loaded soil studied through resonant columns majorly are in the range of 1 to 2 Hz with free vibration and forced vibration, but to start work with the soil sample and to relate the loading properties with the literature is difficult because of the input parameters of dynamic loading. The objective of this study is to provide how much difference occurred in the values of shear modulus (G), damping ratio (D), and peak strain amplitude (γ) on minor changes of input values. The outputs of this research show that shear modulus values increase linearly on change of values of initial frequency and peak strain amplitudes decreases, while there is a minor decrease in the Damping ratio. The acquisition channel gives linear straight values of damping on angular and in the channel of acceleration it provides the wave type variation in values of damping ratio.
