| Abstract | In South East Asian countries, the design and construction of reinforced concrete frame buildings have not taken into account seismic loadings. Thus, many insufficient structural details in beam-column joints including no transverse reinforcement at joints, lap splice in column just above joint level, and construction joints just above and below the beam level in response to seismic loadings have not been examined. These structures need to be investigated to find out their inherent capacity and performance under expected earthquake. Four specimens represented for reinforced concrete beam-column joints of mid-rise buildings in South East Asia were tested at Laboratory of School of Civil Engineering. In this study they are modeled and analyzed by finite element method. The WCOMD-SJ program written and developed by the University of Tokyo is used as the numerical analysis tool. The analysis results are compared to experimental results in terms of load-displacement hysteresis loops, deformations and cracking pattern. The agreement between analysis results and experimental results are judged good. This indicates that, based on well-established models, the finite element models used in this study are suitable and the corresponding analysis results are reliable. Shear transfer mechanisms in these beam-column joints are investigated. Comparisons with available shear transfer models namely Strut and Truss model, Strut and Tie model, and Shiohara's model indicate that Shiohara's model is the most suitable for these beam-column joints. |
