摘要
目前GFRP杆件材性测试相关规范还不完备,特别是采用电测法测试GFRP杆件弹性模量缺少相关资料.采用电阻应变测试法对GFRP杆件的弹性模量测量进行了尝试,结果表明,采用50 mm以上电阻应变片可以有效得到弹性模量测试结果.
Nowadays the standard on the experiments of materials characteristics of GFRP bars is incomplete; the data about the electrometric method on the elastic modulus test of GFRP bars is especially scarce. The electrometric method is introduced to test the elastic modulus of GFRP bars in this paper. The experimental results prove that the electric resistance strain gage with the length greater then 50mm can be adopted to carry out the effective data. The experiment process is presented, the experimental results are discussed,and some advice on the electrometric method application to the modulus test of GFRP bar is made.
