The aim of this research is to get improving of strength and ductility in column specimen given
the GFRP strengthener (Glass Fiber Reinforced Polymer) toward with original column, by using the
cyclic load as the fix representative of quake load. There are two specimens full scale used. They
are C-1 (original column) and C-1G (column with GFRP strengthener 1 layer). From the research
got Pmax sequentially is 278,9 kN and 372.4 kN, and dmax is 53.24 mm and 56.78 mm, each for C-1
and C-1G. For C-1 column, the concrete gets damage in plastic hinge zone at drift ratio 3.5%
indicated by bending of longitudinal steel bar and spalling of cover concrete. The test for C-1G ends
in third cycle at drift ratio 5% and gets damage in fracture of GFRP in plastic hinge zone. The
damage is the changing of resin color the circumferential direction in three spots. They are as long
as 10, 11 and 18 cm. Ductility index taken on three positions are plastic hinge zone, column with a
half high effective and as high as effective column. From the analyze result got ductility index C-1
on the three positions are 1.65; 1.70; 1,97 and ductility index C-1G are 1,44; 1,44 and 1,38 each for
plastic hinge zone, a half high effective and as high as effective column
Key words : ductility, GFRP, strength, external confinement, cyclic
