Abstract
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.
