This paper studies the effectiveness of bonding carbon fiber reinforced polymer (CFRP) with additional wraps or anchors to strengthen reinforced concrete (RC) arches resisting blast loads, which is of great significance to optimize the CFRP strengthening methods. To improve the anti-explosion behavior, RC arches are bonded with CFRP sheets in longitudinal and transverse directions, and anti-explosion behaviors were investigated through experiments. The performance of strengthened arches is discussed in terms of damage degrees in contrast to the un-strengthened arch. Under explosive loading, the resistance of composite arches to spalling, shearing, and bending is much better than that of control arch. The results show that the anti-explosion effect of wrapping or anchoring, which can prevent CFRP debonding or peeling-off, is much better than only bonding CFRP in the longitudinal direction. Besides, simplified analysis models are proposed to assess the blast-resistant capacity of CFRP strengthened RC arches, which show good agreement with the experiment.
