摘要
利用冲击弹性波的冲击回波法、透过法对不同长度、直径为25 mm的钢筋弹性模量进行测试。发现了不同的方法对测试结果的影响,并得出不同测试方法在测试一维杆件的适用范围,对利用冲击弹性波测试结构物弹性模量提供了重要依据。
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.
