ABSTRACT: This paper analyses the
seismic performance of exterior beam-column joints strengthened with
unconventional reinforcement detailing. The beam-column joint specimens were
tested with reverse cyclic loading applied at the beam end. The samples were
divided into two groups based on the joint reinforcement detailing. The first
group (Group A) of three non-ductility specimens had joint detailing in
accordance with the construction code of practice in India IS456-2000, and the
second group (Group B) of three ductility specimens had joint reinforcement
detailed as per IS13920-1993, with similar axial load cases as the first group.
The experimental studies are proven with the analytical studies carried out by
finite element models using ANSYS. The results show that the hysteresis
simulation is satisfactory for both un-strengthened and ferrocement
strengthened specimens. Furthermore, when ferrocement strengthening is
employed, the strengthened beam-column joints exhibit better structural
performance than the un-strengthened specimens of about 31.56% and 38.98 for
DD-T1 and DD-T2 respectively. The analytical shear strength predictions were in
line with the test results reported in the literature, thus adding confidence
to the validity of the proposed models.
