(Test Method)Standard Test Method for Diagonal Tension (Shear) in Masonry Assemblages
Standard Test Method for Diagonal Tension (Shear) in Masonry Assemblages
SIGNIFICANCE AND USE
This test method was developed to measure more accurately the diagonal tensile (shear) strength of masonry than was possible with other available methods. The specimen size was selected as being the smallest that would be reasonably representative of a full-size masonry assemblage and that would permit the use of testing machines such as are used by many laboratories.
Note 1—As a research test method used only for the purpose of evaluating the effects of variables such as type of masonry unit, mortar, workmanship, etc., a smaller size specimen could be used if the available testing equipment will not accommodate a 1.2-m (4-ft) square specimen. However, there is a lack of experimental data that would permit an evaluation of the effect of specimen size on the shear strength or to permit a correlation between the results of small-scale specimen tests and larger specimens.
SCOPE
1.1 This test method covers determination of the diagonal tensile or shear strength of 1.2 by 1.2-m (4 by 4-ft) masonry assemblages by loading them in compression along one diagonal (see Fig. 1), thus causing a diagonal tension failure with the specimen splitting apart parallel to the direction of load.
1.2 Annex A1 provides requirements regarding the determination of the diagonal-tension strength of masonry under combined diagonal-tension and compressive loading.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems, 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.

4. Apparatus
4.1 Testing Machine—The testing machine shall have suf-
ficient compressive load capacity and provide the rate of
loading prescribed in 6.4. It shall be power-operated and
capable of applying the load continuously, rather than inter-
mittently, and without shock. It shall conform to the require-
ments of the Calculation and Report sections of Practices E4.
NOTE 2—In order to accommodate a 1.2-m (4-ft) square specimen
placed in the machine so that its diagonal is in a vertical position, the
machine should have a clear opening height of at least 2.13 m (7 ft).
4.2 LoadingShoes—Two steel loading shoes (see Fig. 2 and
Fig.3)shallbeusedtoapplythemachineloadtothespecimen.
The length of bearing of the shoe shall be 152 mm (6 in.).
NOTE 3—Experimental work has indicated that the maximum length of
1
bearing of the shoe should be approximately ⁄8 the length of the edge of
the specimen to avoid excessive bearing stress.
