Tests have shown that the confinement of the concrete obtained from a suitable arrangement of transverse reinforcement results in a significant increase in both the strength and the ductility of the compressed concrete.

In a general form for rectangular reinforced concrete members it is possible to have quantities of transverse confining steel in x and y directions. We used the proposed stress-strain model by Mander in reinforced concrete corner joints in which loop reinforcement has been provided. Experimental evidence shows that the loop reinforcement in corner joints can increase the efficiency of the joints up to 100 percent of the connecting members namely beams and columns. In the joint the increased strength of the joint with loop reinforcement is attributed to the better confinement of the core with loop reinforcement.
