<p>The strain effect of REBa<sub>2</sub>Cu<sub>3</sub>O<i><sub>y</sub></i> (REBCO: RE = Y, Gd, Sm)-coated conductors (CCs) on critical current (<i>I</i><sub>c</sub>) is one of the most fundamental factors for superconducting coil applications. In this study, we aim to clarify the effect of artificial pinning center shapes on the strain effect in BHO-doped GdBCO CCs<sub>.</sub> To achieve this, we fabricated a Pure-GdBCO CC, a BHO nanorod-doped GdBCO CC and a multilayered-GdBCO (ML-GdBCO) CC, and carried out bending tests. As the result, the strain dependence of <i>I</i><sub>c</sub> for each CC showed an upward convex and the<i> </i>peak strain of the BHO-doped GdBCO CC shifts towards the compressive strain independent of the BHO shapes. In addition, the strain sensitivity of <i>I</i><sub>c</sub> in the GdBCO CCs including BHO becomes smaller. To clarify the difference between the strain sensitivity of <i>I</i><sub>c</sub> and the peak strain among the CCs, we evaluated the residual strain and the slopes of the internal lattice strains against the applied tensile strain (<i>&beta;</i>). From this measurement, the residual strains for the Pure-GdBCO CC and the ML-GdBCO CC were almost the same. In addition, there was no change in the <i>&beta;</i> value between the Pure-GdBCO and ML-GdBCO CCs. These results suggest that the changes in peak strain and strain sensitivity were not related to the internal lattice strain.</p>
