PERFORMANCE OF EXTERNAL REINFORCED CONCRETE BEAM-COLUMN JOINTS MADE OF HIGH STRENGTH CONCRETE
The integrity of beam-column joints in reinforced concrete (RC) frames, especially in a crucial zone, is essential for the satisfactory performance of the whole structure. Therefore, the behavior of external connections between beams and columns is a significant parameter affecting the performance of such R.C frames. An important influence in this regard is the concrete compressive strength, joint reinforcement and relative stiffness of beam and column in each connection, which is itself determined by considerations of geometry and reinforcement percentage. To contribute to a better understanding of the behavior of external beamcolumn joints made of high strength concrete a theoretical study based on the Non-linear finite element analysis is usually appropriate. ANSYS 10[17] software package was used to perform the analysis using the available Solid 65 3-D reinforced concrete element with reinforcing bars. 26 specimens were considered and analyzed. The main parameters were, the details, type and amount of joint reinforcement, the type and amount of beam and column main reinforcement in the joint, the level of axial column load and the concrete strength .The Obtained results were analyzed and discussed. The results were also compared with the obtained results using some available formulae found in the literature. Finally beneficial conclusions and some design recommendations were outlined and given.
