Influence of edge sharpness on the strength of square concrete columns confined with FRP composite laminates

Use of CFRP in Confining High Strength Concrete Columns Subject to Axial Loading

“…The obtained tensile failure strain values for the CFRP jacket were quite lower than the CFRP failure strain, as many authors have already reported [9,11].…”

“…Most of the available experimental data regarding FRP-confined columns have been generated from tests on small-scale concrete cylinders with standard strength. The data available for columns with square or rectangular cross sections have increased over recent years but are still limited [7][8][9]. Also the validation of these results and their applicability to large-scale reinforced concrete (RC) columns is of great practical interest.…”

Performance of externally CFRP confined RC columns with changes in thickness of the wrap, slenderness of the column and shape of the section

“…Chaallal et al, 2003); [9](Y.A. Al-Salloum, 2007). Also the validation of these results and their applicability to large-scale RC columns is of great practical interest.…”

“…The data available for columns of square or rectangular cross sections have increased over recent years but are still limited [7](P. Rochette et al, 2000), [8](O. Chaallal et al, 2003); [9](Y.A. Al-Salloum, 2007).…”

Structural behaviour of square RC columns confined with CFRP wraps

“…However, most of the available studies on the behavior of FRP confined concrete columns have concentrated on circular shaped columns with normal strength. The data available for columns of square or rectangular cross sections have increased over recent years but are still limited [10][11][12][13][14]. Also the validation of these results and their applicability to large-scale RC columns is of great practical interest.…”
