(Test Method)Standard Test Methods for Conducting Strength Tests of Masonry Wall Panels
Standard Test Methods for Conducting Strength Tests of Masonry Wall Panels
SIGNIFICANCE AND USE
4.1 The test methods described in this standard are intended for use as a starting point in developing specific testing protocols for masonry elements.
4.1.1 The testing protocols could be used for general research on the load-deflection behavior of masonry elements.
4.1.2 The testing protocols could be used for qualification of masonry elements and materials by evaluation services and other parties.
4.1.3 The test methods described in this standard are general, and are intended to be adaptable to address a wide range of anticipated support and loading conditions.
4.2 How the test results are interpreted will depend on the intended use of the masonry element being tested.
SCOPE
1.1 These test methods cover methods for determining the strength and load-deflection characteristics of masonry wall elements.
1.2 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.
1.3 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.

Engineered design of masonry structures requires accurate technical data on the strength and
load-deflection behavior of masonry wall elements.These test methods provide a systematic basis for
obtaining such data.
