In 2005, Cabrero and Bayo proposed a design method for semi-rigid joints incorporating the design examples for demonstrating the applicability of the proposed method. Therefore, an ideal semirigid joint is required to consider for the structural design with a large rotational capacity and a predictable flexural strength. The study conducted by Johnson and Hope found that the pin joints are very unpredictable while the rigid joints are often too stiff in relation to their strength, and are expensive.
The intermediate which is non-zero and non-infinite stiffness is semi-rigid joints.

Rigid joints does not allow any rotations between the connected members while pinned joints are characterized by the free rotational movement between the connected elements and prevents the transmission of bending moments. Gene- rally, the connections between the joints are assumed either fully rigid or pinned, which is not an actual behavior to predict joints behavior according to previous investigations. Introduction1 Beam column is the most critical sections in any structural elements and the actual behavior of joints is difficult to idealize and model in real scenario. The results obtained from the two cases were analyzed with consideration of parametric study and variation of the stresses with displacement and are shown with comparative graphic.

In this paper, the flexibility of the reinforced concrete joints was studied under two different cases: in first phase, building having 3 storey including ground floor was taken and is analysed using SAP 2000 and secondly third floor shear wall with l hollow concrete mesh of column section was analyzed in same software and the flexibility of the joints was tested in terms of its stress and displacement parameters using different approaches such as link mass property, end length offset zone, panel zone rotational spring stiffness property. The displacement along the joint section is the most critical one that has to be taken care while designing the structure. The connection between the joints may be assumed as rigid or flexible one and it is not an ideal one to predict the actual behavior of the joint section. A beam-column joint is a crucial zone in any frame structure that transmits the forces at the end of the members in the panel zone.
