| Summary: | 碩士 === 國立交通大學 === 土木工程學系研究所 === 85 === Three different approaches were used in this thesis to measure the dynamic You
ng*s modulus of the concrete, both in the plate and cylinders drilled from the
plate .Including the ultrasonic pulse velocity method, the impact -echo metho
d, and test of stress-strain curve,both normal strength concrete plate and hig
h-performance concrete plate were test by these methods. These dynamic Young*
s modulus were used to calculate vibration frequency of plate by SAP90 and com
pare with the result from the modal testing.The difference of these approaches
with modal testing have a larger value of 6.2% from stress-strain curve test
and a smaller value of 1.7% from the impact each method . The variations from
impact-echo method are very small . All of these results shows Impact-echo met
hod can measure dynamic Young*s modulus of concrete very well.
