In this paper, a static failure test was carried out on a confined concrete beam and a normal reinforced concrete beam. The theoretical and experimental bearing capacity of ordinary reinforced concrete beams and regional confined concrete beams are analyzed. The experimental and theoretical calculation results show that the regional confined concrete beam can effectively increase the bearing capacity of the beam without changing the section size. Since ordinary reinforced concrete participates in the compression zone in order to consider the compression zone, the calculation formula for regional confined concrete beams given in the code is conservative.
