| Abstract: | A study is described that uses the impact-elastic-wave-based echo and refraction method to measuse the elastic modulus of a 25mm-diameter steel rebar with varying lengths.Through laboratory testing,the effeets of different testing methods on the modulds measurements were examined and the suitability of varidls methods for testing a one-dimensinal member was assessed.The results form this study provided important evidences regarding the application of the impact-elastic-wave method in the measurement of elastic modulus of structures. |
