NOTES:

1 E-Glass is type E-CR Glass and meets ASTM D578 E-CR Glass

The above fiber reinforced polymecomposites column casing systems have undergone laboratory testing and are approved for use in limited situations. Advanced composite column casing thicknesses, as shown on the Standard Drawing, are designed to enhance both the shear capacity and increase the lateral confinement of the plastic hinge zone for bridge columns with poor transverse reinforcement details. Material testing standards and provisional specifications have been developed to allow limited field installations for both E-glass (GFRP) and carbon (CFRP) fiber composites, under strict conditions.

Advanced composites systems shall be specified as an alternative if conditions below are satisfied:

  1. Displacement ductility demand not more than 6 for circular columns and not more than 3 for rectangular columns. It may be permissible to use advanced composites on circular columns with ductility demands approaching 8, with the written approval of the Earthquake Engineering Branch and the Design Supervisor
  2. For rectangular columns, the longest dimension is limited to a maximum of 36 inches. Rectangular column side aspect ratio shall not be greater than 1.5. For shear deficient only columns, these limits may be exceeded; however, exceeded limits must be approved by the Earthquake Engineering Branch specialist
  3. For circular columns, the diameter must be 72 inches or less
  4. Lap splices do not exist in expected plastic hinge zones
  5. Composites shall not be used for single column bent structures.
  6. The total axial load (dead load + overturning) is not greater than 0.15 f’cAg
  7. The columns longitudinal reinforcement ratio is not greater than 2.5%
  8. The bridge does not require flame-sprayed plastic
