This report basically discusses the studies and overview of the chosen topic, which is Study on Behavior of Reinforced Beam-Column Joint when Subjected to Seismic Load and the Application of Steel as a Bracing. The situation for building design against earthquake effects in Malaysia is apparently unique. There is no seismic design code as there is no local seismicity, yet the effects of significant regional earthquakes are frequently felt in many high rise buildings in Malaysia. This project is about the application of bracing as a method for strengthening the beam-column joint when subjected to seismic load apart from the gravity loads. The bracing is one of the retrofitting methods in new technology that was brought to embrace the design of reinforced concrete of beam-column joint where it facilitates the strength of the joint. STAADPRO Software is used to assist the calculation of the approximate loads on the reinforced concrete of beam-column joint. Firstly, the building is analyzed and the weakest point of the beam-column joint is determined. At this stage, the chosen steel bracings are proposed and analyzed. The bracings that were used are the Diagonal Bracing and the K-Bracing with different adequate dimensions for each orientation. The parameter that is used as the result to compare is the beam-end displacement in the STAAD. Pro or story drift
