Proposals of Beam Column Joint Reinforcement in Reinforced Concrete Moment Resisting Frame : A Literature Review Study

That the failure of large beam column specimens occurs in the joint rather than in the adjoining members or the beam proves that the joint shear strength of the current methods are inadequate. Moreover, the addition of transverse shear reinforcement in the joint up to a certain limit will increase the shear strength and otherwise it would result in a decrease, if this limit is exceeded. So to increase the shear strength to a greater value, other means are required. With the simplifying assembling and the ductile performance of steel, it is proposed that the use of King-cross steel profile implants at beam-column-joints as a shear reinforcement could be expected to replace the transversal reinforcement and enhance the joint shear strength, ductility and stiffness of the structure.
