Standard Test Method for Diagonal Tension (Shear) in Masonry Assemblages

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 suggestions 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.
1.4 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.

Designation: E 519 – 00 An American National Standard
Standard Test Method for
Diagonal Tension (Shear) in Masonry Assemblages
This standard is issued under the fixed designation E 519; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. 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 diago-
nal (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 determi-
nation 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.
1.4 This standard may involve hazardous materials, opera-
tions, 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 deter-
mine 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 E 4.
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 Loading Shoes—Two steel loading shoes (see Fig. 2 and
Fig. 3) shall be used to apply the machine load to the specimen.
The length of bearing of the shoe shall be 152 mm (6 in.).
NOTE 3—Experimental work has indicated that the maximum length of
bearing of the shoe should be approximately ⁄8the length of the edge of
the specimen to avoid excessive bearing stress.
5. Test Specimens
5.1 Size—The nominal size of each specimen shall be 1.2 by
1.2 m (4 by 4 ft) by the thickness of the wall type being tested.
The 1.2-m dimensions shall be within 6 mm ( ⁄4 in.) of each
other.
5.2 Number of Specimens—Tests shall be made on at least
three like specimens constructed with the same size and type of
masonry units, mortar, and workmanship.
5.3 Curing—After construction, specimens shall not be
moved for at least 7 days. They shall be stored in laboratory air
for not less than 28 days. The laboratory shall be maintained at
a temperature of 297 6 8 K (75 6 15°F) with relative

5.5 Masonry Units—Masonry units shall be sampled and
tested in accordance with the following applicable methods:
Test Method C 67 for clay brick or tile or Method C 140 for
concrete masonry units.
5.6 Grout—When specified, grout shall be sampled and
tested in accordance with Test Method C 1019.
6. Procedure
6.1 Placement of Loading Shoes—Position the upper and
lower loading shoes so as to be centered on the upper and lower
bearing surfaces of the testing machine.
6.2 Specimen Placement—Seat the specimen in a centered
and plumb position in a bed of gypsum capping material placed
