Abstract EN
In an attempt to mitigate the high cost of FRP composite strengthening, an experimental investigation was carried out that sought to achieve efficient and most favorable FRP strengthening using CFRP composite strips.
50 mm wide CFRP composite strips were used in two different spacings (20 mm and 40 mm) to confine columns.
The test results of the column confined with smaller spacing (20 mm) showed significant restraint of axial deformation of the column and enhanced the strength capacity to a maximum of 99.20% compared to that of reference column.
In contrast, the column confined by strips with larger spacing (40 mm) failed by crushing of concrete alone, which occurred even before the CFRP strips reached their ultimate strain.
In addition, the embodied energy that exists in the CFRP strips could not be utilized effectively.
The stress and strength enhancement ratio of this present study was compared with the previous research that has been conducted on columns confined with full wrapping.
From the obtained results, it is recommended that CFRP strips with a spacing of 20 mm be used to improve the strength capacity of the RC column; in addition, this wrapping technique provides economic benefits compared to a column confined with full wrapping.
