摘　　要：以钢筋混凝土简支梁正截面实验教学为例,分析了钢筋混凝土梁、柱轴向应变常用测试方法和存在问题;论述了钢筋混凝土梁柱多点轴向位移式应变仪的研制思路、测试原理;比较了各种轴向应变测试方法的优缺点。Taking the experimental teaching of right section of reinforced concrete simple beam as an example, this essay analyzed the commonly used test methods of axis strain and the existent questions of reinforced concrete members. A new type of test method called multi-spots axial strain sensor was elaborated, the development conception and test principle were also introduced. Through comparison, its superiorities are obvious.
