Applicability and Exclusions

This standard is intended for use in the design of new buildings and other structures constructed of pultruded fiber-reinforced polymer (FRP) composite structural shapes, connections, and prefabricated building products. This standard does not cover tendons and cables. The standard applies to pultruded fiber-reinforced polymer (FRP) structural shapes that have symmetric and balanced glass reinforcement and fiber architecture combined with a polymeric matrix. The design of pultruded FRP structural shapes containing fibers other than glass shall be established in accordance with Section 2.3.2.

Maximum Service Temperature

The maximum service temperature for pultruded FRP structural members, components, and systems designed according to this standard shall not exceed T_g - 40 °F (T_g - 22 °C), in which T_g is the glass transition temperature of the composite system determined in accordance with ASTM E1640.

Units

Where the provisions of this standard require units, they are provided as US customary units, with SI units provided either parenthetically or as footnotes to tables. Many of the equations presented do not require explicit statement of units; in these equations the designer shall use units for all quantities that are consistent.
