Abstract:
In the field of construction, reinforced concrete (RC) column is
fundamental element that hold significant importance as essential
load-bearing constituents. In some cases, there is need to strength
and enhance load carrying capacity of the column for many
reasons such as structural upgrades, aging and deterioration and
seismic retrofitting. Using some strengthening and retrofitting
techniques can reduce risk damage, increase the load capacity and
raise the ductility. One of them is applying flexible near surface
mounted –carbon fiber reinforced polymer (NSM-CFRP) cord.
This study will discuss this technique which is used by making
grooves in the concrete cover and apply the desired material in,
(CFRP will be used here), to examine the effects of used material
on the strength of columns, which is a composite material
comprising high-strength carbon fibers embedded in a polymer
matrix. Analysis and investigation were conducted on strengthened
(RC) column sample using CFRP cords from experimental test and
comparing results with finite element (F.E) method using Abaqus
program. The outcomes show good agreement of results between
the proposed (F.E) model and the experimentally repaired
columns. The parametric study in this research will include:
different shapes of cross-sectional area of the column,
classification of column short and long and the effect of applying
CFRP on these types of (R.C) column.
