|Significance and Use|
5.1 The compressive properties obtained by axial compression will provide information such as: modulus of elasticity, stress at proportional limit and compressive strength for the end support, and lateral bracing condition tested.
5.2 This test method addresses only full-sized specimens for determination of compressive strength and compressive modulus of elasticity intended for application to actual length members with end conditions and lateral bracing as intended.
Note 1: The effective length of the column with respect to buckling is affected by the end conditions. A fixed end condition results in an effective length for buckling that is less than the actual length of the column, by as much as 50 %.
1.1 This test method covers the evaluation of vertical members in axial compression for “full-sized” specimens with various end conditions with constant cross-sections throughout the length.
1.2 This test method is limited to reinforced plastic and polymer matrix composite materials and covers the determination of the compressive properties of structural members. The method is intended primarily for members of rectangular cross section, but is also applicable to irregularly shaped studs, round posts, or special sections.
1.3 This test method covers short-term axial load testing under standard indoor atmospheric conditions. It does not address: sampling, the ability of the material to carry a sustained long-term load, design load derivations, temperature effects, performance under freeze/thaw or salt spray exposure conditions, chemical/UV exposure effects, or engineering analysis/modeling needed to extrapolate the results to conditions other than those tested. Each of these factors, and potentially others, need to be considered by the design professional or product standard development committee before using the information generated by this test method to assess structural adequacy.
1.4 Short sections are not covered in this test method and should be tested using a material test standard such as Test Method or Test Methods .
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.6 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.
