The present study focuses on the pull-out behavior of beam longitudinal rebar with bending and mechanical anchorage from a typical reinforced concrete (RC) exterior beam-column joint. In particular, an optical fiber sensing using the fiber bragg grating (FBG) sensors was applied to experimentally measure the strain behavior of reinforcing bars pulled out. Consequently, the bond behavior between the reinforcing bars and concrete measured by the FBG sensors was significantly different from that by conventional strain gauges. The obtained test results can contribute to clarify the anchorage mechanisms.
