Abstract
Most of the residential buildings were built without following the requirements specified in the design Code of earthquake-resistant building. Such non-engineering buildings (NEB) are susceptible to seismic hazard. Beam-column joint failure is a typical example of structural failure in NEB induced by seismic load. Strengthening of the beam-column joint by mean of external steel plate is expected to increase the seismic performance of NEB. This study aims to find the most effective plate width as a strengthening material for the beam-column joint. ATENA software will be used for the investigation. The structural model is portal structure without strengthening as a control, namely the PU-200 model and with an external steel plate, namely PUP-200 with various width of plates. From the results of the analysis, it is found that strengthening joint with a plate width of 50 mm has better performance than plate widths of 100 mm and 150 mm. The increase performance is quantified in term of increase of load by 14.60%, reduction of displacement by 18.43% and reduction of crack width by 23.65%.
