Experimental Investigation of RC Exterior Beam Column Connection with Eccentric Beam Subjected to Reversible Quasi Static Loads
Abstract: Insufficiency of the
Beam Column Joint (BCJ) caused structures failures particularly in case of the
earthquakes. In most of the buildings, the beam center line was not aligned
with the column center line. So, the effect of the eccentricity of the beam was
studied in this article. Behaviour of reinforced concrete (RC) eccentric
beam-column joint under reversible cyclic loading was investigated
experimentally. The experimental program is one specimen. The specimen
consisted of column and beam. The column divided into symmetry two parts (upper
and lower parts). The beam fixed in middle of the column and it was free end.
The main parameter was the effect of the eccentricity of the beam center line
about the column center on behaviour of RC BCJ. The specimen was tested under
reversible ten cycles. The horizontal displacement for the column and the
vertical deflection at free end of the beam were recorded at each cycle. The
crack pattern of the tested specimen was studied at every cycle in details. It
was noticed that the eccentricity of the beam has concentrated more stresses on
the joint side close to the eccentricity. The failure took place at the joint
due to its weakness.
