Abstract: This research offers an experimental study of the behavior of reactive powder concrete (RPC) deep beams with openings
externally bonded by carbon fiber-reinforced polymer (CFRP) strips. The beam specimens are classified into three categories. The first
category contains two RPC deep beams without strengthening. The second category has six RPC deep beams strengthened with different
schemes of CFRP strips without mechanical anchorage. The last category includes four RPC deep beams strengthened with CFRP strips and
using mechanical anchorage (bolts). The results showed that using a CFRP system as an external strengthening technique has an important
effect on the overall response of the tested beam specimens. The ultimate strength of the deep beams with openings increased by 11%–94%
compared to nonstrengthened specimen
