| 要旨 | This paper discusses the performance of pretensioned prestressed concrete beams strengthened in shear using externally bonded CFRP sheets. The shear capacity and stiffness in the post-cracking region were increased with smaller spacing between the strips of CFRP sheets. Furthermore, the strip spacing, wrapping types and thickness of CFRP sheets influenced failure behaviors of the strengthened PC beams. Besides, the equations in the design guidelines of ACI and JSCE overestimated the shear capacity carried by bonded CFRP sheets for strengthening PC beams. |
