This paper studies the efficiency of applying an engineered cementitious composite (ECC) layer to tensile surface (RC) beams that were previously strengthened using externally bonded (EB) carbon fiber-reinforced polymer (CFRP) laminates. One control and ten RC produced tested utilizing a four-point loading regime. For beams, two kept only CFRP, additional ECC layers added rest beams. The CFRP w...

The study presents the performance of flexural strengthening concrete members exposed to partially unbonded prestressing with a particular emphasis on amount (0, 14.2, and 28.5%) cut strands-symmetrical asymmetrical damage. In addition examining influence strands remaining capacity post-tensioned effectiveness carbon fiber reinforced polymer laminates restoration, investigated results rectangul...
