| Summary: | This paper presents the experimental and finite element (FE)
investigations carried out on reinforced concrete (RC) beamcolumn
joints with vertically distributed longitudinal reinforcement
layers along its beam. Four full-scale interior beam-column joints
with varying reinforcement within the beam are subjected to a
constant column axial load and quasi-static horizontal cyclic load.
The experimental results highlight and discuss its joint behavior
such as hysteresis loops, cracking patterns, and failure mechanisms.
The FE numerical models are validated by comparing with the
experimental results obtained from tested specimens and
previous research. Parametric studies are performed to investigate
the complex behavior of the joints under the influence of axial
loads, vertically distributed reinforcement layers, and in the
amount of reinforcement provided. |
