FRP as a Retrofitting Solution for Columns

Columns in buildings and bridges often corrode with aging and require repair and strengthening. Construction errors can also lead to weaker columns that require strengthening. Virtually all concrete columns constructed prior to the mid-1970s when modern earthquake codes were developed are unsafe when subjected to seismic loads. In all these cases, FRP offers a fast and cost-effective repair alternative.

Features & Benefits

Advantages of repair of columns with FRP include:

  • Repairs are applicable to all materials (steel, concrete, timber, etc.)
  • Can increase axial, shear and flexural capacity of columns
  • Significantly improve confinement and ductility of column
  • Minimal increase in column dimensions
  • Repairs are fast with minimal disruption of service
