Abstract:
Retrofitting of currently used buildings has come into question with the determination of
buildings’ performance levels due to earthquake force effect. In this sense, lots of retrofitting
techniques have been applied for the retrofitting of current buildings. Columns, beams, joints and
slab can be reinforced on the basis of member, with the retrofitting techniques. By this way,
building safety is provided by increasing the performance level of the buildings. Within the
scope of this study, force-deformation relationship of a single column reinforced with FRP (Fiber
Reinforced Polymer) compared with not reinforced column was analysed with regard to finite
element method. In the analyses, a column in 300x300 mm in size, 2000 mm in height was
modelled. Load was applied step by step as lateral load from 50 nodes which are on 1/7 top of
column. After the force-displacement relationship of not retrofitted column was revealed,
analysis was repeated by modelling FRP material through plastic hinge area of not damaged
column. In conclusion, it is found out that FRP material increases energy consumption capacity
of a single column up to 30%.
