COMPARATIVE STUDY ON RC BEAM COLUMN JOINT USING BOTH ANALYTICAL AND EXPERIMENTAL METHOD Gopi raju D1, Dr. P. Parthiban2 M.Tech Student 1 & Asso.

The behaviour of beam - column joints are based on the strength, stiffness and ductility of the reinforced concrete structure. Beam to column joints are one of the members in reinforced concrete structures and these joint locations are always at risk fpr failures.
column joints are foremost weakend elements. The main importance of beam - column joint is that they can stabilize the structure, if failure occurs at a joint, complete collapse will starts. Beam - column joint is one of the important tie up part to convey loads to next column and beam. Most of the failures are formed at joint due to poor detailing of shear reinforcement. 1.1. TYPES OF JOINTS:
The main aim for choosing this topic is generally failures are formed at the location of beam - column joint. If these beam - column joints are not designed properly, different types of failures may happen. A building beam - column joint connects other several joints they can work together and resist against failures. Most of failures frequently occurs at the exterior beam to column joints compared to interior joints. In the present work as per IS 456 - 2000 beam - column joint is manually designed and casted. After 28 days of curing this joint tested in the laboratary. The same design specifications of beam - column is modelled in Ansys software on the basis of finite element method and results are carried out. After getting the results, compared to both experimental and analytical results.
Key Words: Beam - column joint, Ansys, Loading frame, Reinforcement detailing.

Beam - column joints are the foremost crucial elements in reinforced concrete structure. The main function of providing the beam - column joint in concrete building structures is to transfer the load to remaining members effectively and to continue the structural action between the members. In reinforced concrete structure, the segment of column that is common to the depth of beam at its intersection is called beam to column joint. During ground movements beam-column joints overcome the large forces or lateral forces.Its behaviour plays an important role in the response of reinforced concrete structure.Because of lateral forces,high shear forces are developed at the beam - column joint,if its fails to resist the forces then failure may happen.

4. Interior joint 5. Exterior joint 6. Corner joint 7. Planner joint Interior joint : When four beam frames are in contact with the portion of column, it is called as an interior joint. Exterior joint : When one beam is in contact with the column and the other two beams joins the joint in perpendicular direction, that type of joint called as exterior joint. Corner joint : When two beam faces frame into portion of two side faces of column is called as corner joint. ISO 9001:2008 Certified Journal
