Abstract -In Reinforced Concrete Framed Structure, the
considered. The various load combinations considered. Following are some of them,
beam column Junction is Critical Zone. Especially when it experiences lateral loads, joints Provides a structures stability and forces at the end of member are transmitted. The beamcolumn joint is one of the most crucial parts of reinforced concrete constructions because it frequently experiences failure in a beam. The joints should be strong and rigid enough to resist the internal forces generated by the frame members. The Present paper is based on using high grade concrete at beam column junction. Structural model is prepared and analysis is done for the beam and node displacement.

1.INTRODUCTION In a reinforced concrete frame construction, a beam-column joint—where the elements are joined in all three directions—is an extremely important zone—is where the elements come together. The stability of a structure is ensured by joints, which also transmit forces at the ends of the members. The beam-column joint is one of the most critical parts of reinforced concrete constructions because beam failure frequently occurs at this point. Their determined behavior is brought on by a sudden change in shape and a complex stress distribution at the joint. Early on, the design of joints in structures made of reinforced concrete was mostly restricted to meeting anchorage requirements. In succeeding years, the behavior of joints was found to be reliant on a number of factors related with their geometry; amount and detailing of reinforcement, concrete strength and loading pattern. Present Paper is based on the to prepare structural model by using staad pro and analysis is done for node and beam displacement to increase joint Stiffness.

2. Methodology By using Staad pro software, two bay symmetrical model prepared, symmetrical model was prepared as we only focus on effect of high-grade concrete at the joints. Height of each floor was 3m and center to center distance of bay was 5m. also dimensions of beam and column were assumed. Density of concrete were assumed to be 25KN/m 3 , modulus of elasticity was calculated. Seismic Load in both directions i.e. X and Z direction, Live Load and Dead Load these loads are
