Combining two technologies of pasting fiber reinforced composite board (FRP) and externally reinforced steel plate concrete structure, fiber-reinforced composite material and steel plate composite reinforced concrete structure technology can effectively improve the stress performance of concrete reinforced structure. To explore the effect of the new technology steel plate anchoring FRP slab concrete beams and the effect of different damage levels on the reinforcement effect, in this paper, the author made 3 FRP reinforced beams with damage rates of 20%, 40%, and 60%, 1 RC beam with FRP plate only and an ordinary RC beam to analyze the reinforcement effect of the new process steel plate anchored FRP plate and the bearing capacity and plastic performance of the reinforced beam with different damage rates. The results show that the new technology steel plate anchoring FRP plate reinforcement technology can effectively prevent the occurrence of early peeling failure, improve the ductility and bearing capacity of the reinforced beam, and significantly increase the utilization rate of the FRP plate; as the damage rate increases, the ultimate bearing capacity of the reinforced beam increases, but the ductility is significantly reduced.

Metal selenides and their derivatives have attracted great attention and are regarded as promising electrodes materials due to their superiority of electrochemical activity and conductivity. Therefore, we design a facile...

In order to explore the influence of length and width of CFRP as well as anchor spacing on the reinforcement effectiveness of CFRP plates on reinforcement concrete beams (RC beams) under secondary load, 7 anchored damaged FRP reinforced concrete beams are used as test beams, 1 unanchored beam is used as a control beam, and structural indicators such as ultimate load and bending strength are analyzed in the result. The conclusion is that composite CFRP plate can effectively prevent the early peeling and failure of carbon plates and improve the ultimate bearing capacity of the beam. When the width of the CFRP plate decreases, the thickness increases and the steel plate anchor spacing increases appropriately, the ultimate bearing capacity and ductility of the beam are significantly improved.
