摘　　要：在钢梁与混凝土墙连接节点抗震性能试验研究中,在混凝土墙内部和钢梁翼缘的测点处同时布置了FBG应变传感器和电阻应变片进行应变采集,并将两者测得数据进行对比分析。结果表明:FBG应变传感器具有良好的抗干扰性和稳定性、安装和使用过程中不易损坏;表面式FBG应变传感器所测结果与电阻应变片所测结果基本一致,而内埋式FBG应变传感器所测结果与电阻应变片所测结果有一定差距;表面式FBG应变传感器具有较好的可用性与适用性。In the seismic performance experiment of connection joint between steel beam and concrete wall,fiber bragg grating（FBG） sensors and resistance strain gauges were located at the same measuring point in the concrete wall and the flange girth of the steel beam,contrast was made between FBG senor and resistance strain gauge.Analysis results show that the FBG senor has better antiinterference ability and stability,is not easily damaged during the installation and use process,the measuring results of surface FBG sensor and resistance strain gauge are consistent,but the measuring results of the buried FBG sensors and resistance strain gauge are inconsistent,the surface FBG sensor has good availability and suitability.
