    abstract = {The column is an important structural component for supporting axial load, bending moment and
shear force. Damage caused by shear failure is seen as the most dangerous because the damage can cause
structural collapse suddenly. Therefore, the columns of a building that has inadequate shear strength, so that,
needs to be strengthened with appropriate methods. One method that is appropriate to maintain the stability
of structural elements of the column is a strengthening. In this study, the materials to be used as a
strengthening of the GFRP material therefore has a a high tensile strength light weight and it’s easy in
implementation. The method used in this study is a method of strengthening with Glass Fiber Reinforced
Polymer (GFRP) with model testing of concentric loading. In this study, the specimen will be used 9 specimens
of the circular columns with models of variation is 3 specimens of RC circular columns without the use of GFRP,
3 specimens of RC circular columns, 3 specimens of RC circular columns with 1 layers of Glass fiber Reinforced
Polymer (GFRP) and 3 specimens of RC circular columns with 2 layers of Glass fiber Reinforced Polymer (GFRP).
The circular column with a diameter of 130, height 700 mm with reinforcement longitudinal 6ø10 and spiral
reinforcement for the transverse reinforcement is ø 8-50 mm. The experimental results show an increase in the
capacity of a circular column to one GFRP layer happen a increasing the strength of 12.17% if it’s compared with
no use of GFRP material and the circular column capacity of 1 GFRP layer to 2 GFRP layers have a increasing
the strength of 8.53%}
