摘　　要：在钢梁与混凝土墙连接节点抗震性能的试验研究中,于钢梁翼缘同一测点处同时布置了表面式FBG应变传感器和电阻应变片进行应变采集,测量结果显示,两者的测量效果基本一致,同时表面式FBG应变传感器还具有使用便捷,不易损坏的优点,因此在结构试验中采用表面式FBG应变传感器测量构件的表面应变是完全可行的。In the experiment of the behavior of theconnection between steel beam and concrete wall, surface FBG sensor and resistance strain gauge were located at the same measuring point of the flange girth of the steel beam. Measuring results show that the measuring effectiveness of both methods are uniform. And the surface FBG sensor has the merits of using conveniently and non-vitiating. So using surface FBG sensor to measure the surface strains of structural members in structure experiment is feasible.
