    Significance and Use

    This test method for transverse shear strength is intended for use in laboratory tests in which the principal variable is the size or type of FRP bars. The test may be used for smooth round rods or on bars with a textured or undulating surface added to promote bond of the bars to Portland cement concrete. This test method establishes values of transverse shear strength for material specifications, quality control, quality assurance, research and development, and may also be used for structural design purposes.

    Experience with this test method and the accompanying fixture is primarily with smooth rods and textured bars with diameters ranging from 6 mm to 25 mm [0.25 in. to 1 in.]. The method may be used for rods or bars of larger diameters, but the overall geometry of the test fixture may need to be increased.

    1. Scope

    1.1 This test method specifies the test requirements for (FRP) composite smooth round rods and textured bars for determining the transverse shear strength via a double shear fixture. FRP rods and bars are often loaded in transverse shear when these elements are used as dowels in concrete pavements, as stirrups in concrete beams, or as shear reinforcements in glued-laminated wood beams, for example.

    1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

    1.2.1 Within the text, the inch-pound units are shown in brackets.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
