Comparison of Static and Dynamic Modulus of Elasticity of Concrete Specimens

Popis výsledku v původním jazyce

The paper presents comparison of results of two methods for elastic modulus evaluation of concrete specimens. The first method used for the dynamic modulus of elasticity evaluation was resonant method. The major advantage of this method is its nondestructive character. The excitation was done by the impact hammer and the response was measured by piezoelectric acceleration transducers. Natural frequencies were evaluated from resonant peaks of Frequency Response Functions. The dynamic modulus of elasticity was calculated on the basis of natural frequencies using relations for structures with continuously distributed mass. Then we continued with standard destructive compression tests. At the end of the paper, the results of comparison of static and dynamic moduli of elasticity are summarized.
