摘　　要：在两个钢梁-混凝土墙节点中的同一位置分别设置光纤光栅传感器与应变片,通过对比光纤光栅传感器与应变片显示的应变结果,对整个试件的受力过程进行测量和分析。结果表明:光纤光栅传感器比应变片的效果更好,测得的数据更准确,从而证明了光纤光栅传感器在土木工程检测应用中的可行性。FBG sensors and strain gauges were set respectively at the same location between two rigid conjunction nodes of steel beam and concrete wall. The strain values of the test specimen were measured through the sensors and gauges. The force process of the entire specimen was analyzed. The FBG sensors has better measuring effect than strain gauges, and the measured data are more accurate, thus proving the feasibility of FBG sensors for civil engineering detection.
