ASTM E2126-07

Standard Test Methods for Cyclic (Reversed) Load Test for Shear Resistance of Walls for Buildings

SIGNIFICANCE AND USE
These test methods are intended to measure the performance of walls subjected to earthquake loads. Since these loads are cyclic, the loading process simulates the actions and their effects on the walls.
SCOPE
1.1 These test methods cover the evaluation of the shear stiffness, shear strength, and ductility of a wall assembly, including applicable shear connections and hold-down connections, under quasi-static cyclic (reversed) load conditions.
1.2 These test methods are intended for wall assemblies constructed from wood or metal framing with solid sheathing or other bracing methods or structural insulated panels.
1.3 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.
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.
