Abstract - The part of the column that is common to beam at their intersection in a building is known as the beam column joint. The fundamental purpose of beam column joint in reinforced concrete buildings is to transfer the load from connecting members effectively, while subjected to both gravity loads and seismic forces. The beam column joint is a portion that needs to resist lateral, longitudinal loads along with moment. They are the weakest link in RC moment resisting frame. Primarily due to the inadequate shear strength at the joints. In order to withstand these loads without causing damage, reinforced concrete frames must worksatisfactorily in extreme load conditions at beam column junction. Thus, proves to be a crucial aspect of structural design. The use of carbon fiber reinforced polymer (CFRP) materials in the retrofitting of beam column joints is notable, due to its high strength, stiffness, and corrosion resistance. Ansys Workbench is a powerful software tool for analyzing and designing beam- column joints in India. It enables detailed simulations and analysis, reducing the need for physical testing and streamlining the retrofitting process. With its advanced features and rapid design iterations, it enhances project efficiency and reduces costs. The present study focuses on the analysis and retrofitting of beam-column joints using carbon fiber reinforced polymer (CFRP) materials in Ansys Workbench, in the 2022 R2 Student and 2022 R1 Teaching versions. The study highlights the Total deformation and Maximum principal stress of retrofitted Beam Column joints compared to their original condition.
CFRP jacketing in retrofitting beam column joints and assess its effectiveness in improving the overall strength and stability of the structure. We will also utilize Ansys Workbench software to perform Finite Element Analysis (FEA) simulations and gain a deeper understanding of the structural behavior before and after retrofitting. Furthermore, this report will include a detailed cost analysis of the retrofitting process, taking into account the cost of materials, labor, and project timeline to provide a comprehensive understanding of the financial feasibility of this retrofitting technique. 1.2 Beam Column Joint: The beam-column joint is one of the critical elements in reinforced concrete structures. It connects the vertical and horizontal members, thereby transferring the loads from the slab and beam to the columns. The behavior of the beamcolumn joint under various loads is of utmost importance for the safety and durability of the structure. The shape, size,and detailing of the beam-column joint have a significant influence on its performance. The integrity of the beamcolumn joint plays a vital role in the overall strength of the structure. Any failure or deformation in the joint can lead to the collapse of the structure. The reinforcement in the beamcolumn joint is critical for its performance. The steel reinforcement provides strength and ductility to the joint, enabling it to resist the forces induced by the loading conditions. The detailing of the reinforcement, including its spacing, arrangement, and development length, is critical for the proper functioning of the joint.

1.3 Retrofitting:
1. INTRODUCTION
Retrofitting of structures has become increasingly important due to the aging of infrastructure, increased loads, and changes in design codes. Retrofitting is the process of strengthening or upgrading existing structures to improve their performance under current and future loading conditions. The retrofitting of structures involves adding new elements or strengthening existing ones to improve their load-carrying capacity, ductility, and resistance to earthquakes and other natural disasters. Retrofitting of joints involves increasing the size and strength of the joint to
1.1 Opening Remark: The retrofitting of existing concrete structures has become an increasingly important aspect of structural engineering, particularly when it comes to enhancing the strength and durability of beam column joints. Carbon fiber reinforced polymer (CFRP) jacketing is a popular retrofitting technique that can effectively increase the structural capacity of these joints. In this report, we will explore the use of
