Sažetak
Experimental determination of dynamic modulus of elasticity of fiber-reinforced concrete (FRC) by using impact hammer is based on measuring resonant frequencies of flexural vibrations in prismatic specimens. The natural frequencies are determined as resonant peaks from frequency response function (FRF), which is obtained by measuring the excitation and response function. The determination of the natural frequencies in this way represents an improvement over standardized test methods. The dynamic modulus of elasticity is determined using fundamental resonant frequency according to relations given in standards. The results are compared to the modulus of elasticity obtained by correlation with compression strength.
