Parameters affecting the accuracy of bender element test results and interpretation of the result

Accurate measurement and the impact of various factors on the trend of changes in soil dynamicparameters at different strain levels have a very important role in seismic response analysis and designof structures. These parameters (damping and shear modulus) are divided into two parts by linearbehavior (soil elastic behavior at very small strain levels) and nonlinear behavior (elastoplastic andplastic behavior at medium and large strain levels) by changing the strain level.Therefore, in thisstudy, while examining the theoretical foundations and technical literature related to shear wavevelocity measurement using bender elements (BE), how to interpret and analyze the results,uncertainties and the effect of effective parameters in accurate modulus measurement Shear (Gmax) isdiscussed. Suggestions have also been made to increase the response accuracy of bender elements.
