CFRP column wrapping for increased load carry capacity

Load carrying capacity can be increased by wrapping columns horizontally. The strength added is similar what you get from the spiral or hoop rebar typically included in these columns.

If the design load is being increased or if there is section loss in the existing reinforcing steel, CFRP can be used to remedy this situation and help prevent a compressive failure in the column.

Other possible solutions to handle such situations are to add a reinforced concrete jacket or additional columns, CFRP is usually the most economical solution and can be installed in much less time.
